NFL and college football handle overtime differently. Both aim to break a tie after regulation, but the rules governing possessions, field position, scoring, and game length are not the same.
In the NFL, overtime uses a game clock, normal field position, and a modified sudden-death format. College football removes the game clock and gives each team a scoring opportunity from the opponent’s 25-yard line during the first two overtime periods.
One important change came in 2025, when the NFL extended its postseason-style possession rule to regular-season overtime. Both teams now generally have an opportunity to possess the ball, even if the opening team scores a touchdown.
Here is how the two systems work and why their differences matter.
NFL vs. College Football Overtime: Quick Comparison
| Rule | NFL Regular Season | NFL Playoffs | NCAA College Football |
|---|---|---|---|
| Overtime length | 10 minutes | 15-minute periods | No game clock |
| Starting field position | Determined by kickoff | Determined by kickoff | Opponent’s 25-yard line |
| Possessions | Both teams generally get an opportunity | Both teams generally get an opportunity | One possession each in the first two OTs |
| Opening-drive touchdown | Does not automatically end the game | Does not automatically end the game | Opponent receives its possession |
| Sudden death | Applies after both teams have had an opportunity, subject to exceptions | Applies after both teams have had an opportunity, subject to exceptions | No traditional sudden-death drive |
| Two-point conversions | Normal conversion rules | Normal conversion rules | Mandatory after TDs in second OT |
| Third overtime | Not applicable | Additional timed periods as needed | Alternating two-point attempts |
| Can the game end in a tie? | Yes | No | No |
The biggest difference is that NFL overtime still resembles a normal football game, while NCAA overtime becomes a series of short-field scoring opportunities.
How NFL Overtime Works
NFL Regular-Season Overtime Rules
The NFL regular season uses one 10-minute overtime period.
After regulation ends in a tie, officials conduct a coin toss. The winning team can choose whether to receive, kick, or defend a particular goal.
The overtime period begins with a kickoff, and teams operate under normal football rules, including punts, field goals, first downs, and clock management.
Under the rules adopted for the 2025 season, both teams generally have an opportunity to possess the ball.
An opening-drive touchdown no longer automatically ends a regular-season game.
For example:
- Team A receives the opening kickoff.
- Team A scores a touchdown.
- Team B receives an opportunity to possess the ball.
- Team B must respond to avoid losing.
If Team B also scores a touchdown, its conversion decision can determine whether the game ends or continues.
Once both teams have had their opportunity, the game enters a sudden-death phase in which the next score wins.
There are important exceptions. A defensive score on the opening possession can end the game immediately. In addition, the regular-season overtime clock is limited to 10 minutes, so the second team is not guaranteed to complete a possession before time expires.
If the score remains tied when overtime expires, the game ends in a tie.
NFL Playoff Overtime Rules
The NFL playoffs use a similar possession principle, but postseason games cannot end in ties.
The main differences are:
- Overtime periods last 15 minutes.
- Both teams generally receive an opportunity to possess the ball.
- A touchdown on the opening offensive possession does not automatically end the game.
- Additional overtime periods are played until a winner is determined.
The NFL introduced its postseason possession rule in 2022 following concerns about playoff games ending before both offenses could take the field.
The rule was used in Super Bowl LVIII, when the Kansas City Chiefs defeated the San Francisco 49ers in overtime.
Unlike the regular season, playoff overtime continues as long as necessary to determine a winner.
When Does Sudden Death Apply in the NFL?
Sudden death means the next score ends the game.
Under the current NFL system, it generally begins after both teams have had an opportunity to possess the ball and the score remains tied.
Consider this example:
Team A receives the opening kickoff and scores a field goal.
Team B then scores a field goal.
Because both teams have possessed the ball and the score is tied, the next score wins.
If Team B instead scores a touchdown on its possession, Team B wins immediately.
This format changes the importance of the opening coin toss. Receiving first can still be advantageous, but the receiving team no longer has the same immediate touchdown-to-win opportunity it had under the previous regular-season rules.
How NCAA College Football Overtime Works
College football follows a different structure.
Rather than continuing with kickoffs and normal field position, NCAA overtime gives teams short-field scoring opportunities.
There is no game clock during overtime possessions.
First Overtime: Start at the 25-Yard Line
Each team receives one possession beginning at the opponent’s 25-yard line.
The team can score through a touchdown or field goal, just as it would during regulation.
For example:
Team A begins at Team B’s 25-yard line and scores a field goal.
Team B then begins at Team A’s 25-yard line.
If Team B scores a touchdown, it wins.
If Team B also kicks a field goal, the game advances to a second overtime.
If Team B fails to score, Team A wins.
Because the responding team knows the first team’s result, it can make fourth-down decisions with more information.
This is one reason many college coaches prefer to play defense first after winning the overtime coin toss.
Second Overtime: Two-Point Conversions Become Mandatory
The second overtime follows the same basic possession format.
Each team again starts at the opponent’s 25-yard line.
However, there is one major change:
Teams that score touchdowns must attempt two-point conversions instead of kicking extra points.
This increases the importance of short-yardage offensive execution.
A team that scores a touchdown must decide how to attack the defense from the 3-yard line rather than relying on a routine extra-point kick.
If the teams remain tied after their second-overtime possessions, the format changes again.
Third Overtime and Beyond: Two-Point Conversion Attempts
Beginning with the third overtime, NCAA teams no longer receive full possessions from the 25-yard line.
Instead, they alternate two-point conversion attempts.
Each team receives one attempt per overtime round.
For example:
- Team A converts its attempt and earns two points.
- Team B fails its attempt.
- Team A wins.
If both teams succeed or both fail, another overtime round is played.
This format continues until one team finishes a round with more points than the other.
The system was introduced to reduce the number of plays required during extremely long overtime games.
It also places greater emphasis on goal-line play design, defensive coverage, and execution under pressure.
Five Key Differences Between NFL and NCAA Overtime
1. NFL Overtime Uses a Game Clock
NFL overtime operates under a time limit.
In the regular season, teams have 10 minutes to determine a winner.
That makes clock management important, particularly when a team needs to respond to an opponent’s opening score.
A long possession can consume much of the available time.
College football eliminates the game clock during overtime. Teams still use a play clock, but there is no overall time limit on the number of overtime rounds.
This allows college games to continue until a winner emerges.
2. College Teams Start in Scoring Range
NFL overtime begins with a kickoff.
An offense may need to move most of the length of the field to score.
Punting, kickoff returns, and field position remain important.
College teams start at the opponent’s 25-yard line during the first two overtime periods.
They are already within potential field goal range, although the actual likelihood of making a kick depends on the kicker and conditions.
As a result, college overtime emphasizes red-zone execution more heavily than NFL overtime.
3. Both Leagues Give Teams Scoring Opportunities Differently
Since the NFL’s 2025 rule change, the distinction is no longer simply that college football guarantees both offenses a possession while the NFL does not.
The NFL now generally gives both teams an opportunity to possess the ball in regular-season and postseason overtime.
However, the regular season still has a 10-minute limit.
That means the clock can prevent the second team from completing its possession.
College football avoids this issue by removing the game clock and using alternating possessions.
During the first two overtime periods, both teams receive their opportunities before the result is determined, except where a defensive score ends the contest.
4. College Football Has Mandatory Two-Point Attempts
NFL teams follow normal touchdown conversion rules during overtime.
After scoring a touchdown, a team can generally attempt an extra-point kick or a two-point conversion when a try is required.
College football changes the conversion rules as overtime progresses.
In the first overtime, teams may kick an extra point or attempt two points.
In the second overtime, two-point attempts are mandatory following touchdowns.
From the third overtime onward, the game consists of alternating two-point attempts.
This makes the college format increasingly focused on short-yardage execution.
5. NFL Regular-Season Games Can End in Ties
An NFL regular-season game can finish tied if neither team leads when the 10-minute overtime period expires.
A tie counts as half a win and half a loss when calculating a team’s winning percentage.
NFL playoff games cannot end in ties.
College football also requires a winner, regardless of how many overtime rounds are necessary.
How Overtime Rules Affect Coaching Strategy
NFL: Clock Management and Possession Decisions
NFL coaches must account for both the score and the time remaining.
Since both teams generally receive a possession opportunity, the opening team’s objective is no longer simply to score a touchdown and end the game.
A first-possession touchdown still puts substantial pressure on the opponent, but the opponent may respond.
Fourth-down decisions also depend on the situation.
For example, a team trailing by a touchdown on its responding possession may need to attempt a fourth-down conversion rather than punt.
A team responding to a field goal knows that another field goal can keep the game alive, while a touchdown can win it.
In the regular season, coaches must also consider the possibility of the overtime clock expiring.
NCAA: The Advantage of Knowing the Target Score
In college overtime, the team playing offense second has valuable information.
If the first team scores a touchdown, the second team knows it needs a touchdown to stay alive.
If the first team kicks a field goal, the second team can choose between matching that score or pursuing a touchdown to win.
If the first team fails to score, the second team may only need a field goal.
That information can influence fourth-down decisions and play selection.
It does not guarantee that the second team will win, but it gives coaches a clearer picture of the required outcome.
Two-Point Plays Become Critical in College
College coaches must prepare for a format that changes after each of the first two overtime periods.
By the third overtime, there are no normal offensive drives.
Teams rely on plays designed specifically for short-yardage scoring situations.
Common concepts include:
- Quarterback runs and option plays
- Quick passes against man coverage
- Motion designed to reveal defensive assignments
- Tight end routes near the goal line
- Run-pass options that exploit defensive alignment
The exact strategy depends on personnel, defensive tendencies, and field position.
Why Did the NFL Change Its Overtime Rules?
For years, NFL overtime rules attracted criticism because the team receiving the opening kickoff could win with a touchdown before its opponent’s offense entered the field.
The issue became particularly prominent following the Kansas City Chiefs’ overtime victory against the Buffalo Bills in the 2021 season’s AFC Divisional Round.
The Chiefs scored a touchdown on the opening overtime possession, ending the game without Buffalo receiving an offensive opportunity.
In 2022, the NFL approved a postseason rule allowing both teams an opportunity to possess the ball.
In 2025, the league extended that principle to regular-season overtime.
The regular-season period remained 10 minutes, however, preserving the possibility of a tie.
The change reduced the importance of scoring a touchdown on the opening possession as an automatic game-ending result.
It did not eliminate the importance of the coin toss, field position, or clock management.
Why Does College Football Use a Different Overtime Format?
College football adopted its current style of overtime in 1996, replacing the possibility of ties with alternating scoring opportunities.
The system gives both teams an opportunity to score without requiring full-field drives.
Over time, the NCAA adjusted the format to address concerns about lengthy games and the number of additional plays.
The current approach uses full possessions in the first two overtime periods, followed by alternating two-point attempts beginning in the third.
The result is a format that can produce a winner without requiring repeated full offensive possessions.
It also creates a different competitive environment from the NFL, where field position, punting, and time management remain central.
NFL vs. NCAA Overtime: Common Questions
Can an NFL game end in a tie?
Yes. NFL regular-season games can end in ties if the score remains even after the 10-minute overtime period.
Playoff games continue until a winner is determined.
Does an opening-drive touchdown win NFL overtime?
Not automatically.
Under the rules adopted for the 2025 season, both teams generally have an opportunity to possess the ball, even if the first team scores a touchdown.
A defensive score can create an exception, and the regular-season time limit still applies.
Does each NFL team get the ball in overtime?
Both teams generally have an opportunity to possess the ball.
However, in regular-season overtime, the 10-minute clock can expire before the second team completes its possession.
Where does college football overtime start?
During the first two overtime periods, each team begins its possession at the opponent’s 25-yard line.
Starting with the third overtime, teams alternate two-point conversion attempts instead.
When do two-point conversions become mandatory in college overtime?
Two-point attempts are mandatory following touchdowns in the second overtime.
Beginning with the third overtime, each team’s entire scoring opportunity consists of a two-point attempt.
Can NCAA football games end in ties?
No. NCAA overtime continues until one team wins.
Final Thoughts
NFL and NCAA overtime both provide a way to resolve games tied after regulation, but they use different approaches.
The NFL retains the game clock, kickoffs, normal field position, and a modified sudden-death system. Since 2025, both teams generally have an opportunity to possess the ball, even following an opening-drive touchdown.
College football removes the game clock and begins overtime possessions at the opponent’s 25-yard line. After two overtime periods, the game switches to alternating two-point attempts.
For fans, the most important distinction is what happens after the first team scores.
In the NFL, the response depends on possession rules, the clock, and whether both teams have had an opportunity.
In college football, the responding team knows exactly what it needs to match or beat before the next overtime round.
Understanding those differences makes overtime decisions easier to follow—and helps explain why coaches approach the same tied score very differently in the two leagues.
