How about a field goal shootout , kinda like the penalty kicks in soccer overtime?
It would be fun
Start from the 40 yard and keep increasing 5 yards ...until someone misses
Ouch.. Too much pressure and importance on the kickers, who only do one thing (in soccer the guys kicking penalties also played the game).
How about this:
--Sudden death where each offense gets the ball.
--Each offense starts on their own 40 yard line and tries to score. Doesn't matter if it's a touchdown or field goal. In OT each kind of score is equal. (for record books td is still td and field goal a field goal)
--First team not to score when the other team does score loses.
--A turnover on which a score is made wins the game, regardless of whether the other offense had a chance. Otherwise, the team that recovered the turnover (fumble or interception), starts their offense from point of turnover (after tackle) or from their own 40, whichever is better.
Seems to me that would be pretty exciting sped up football in OT.
That's a variation of a "Kansas City Tiebreaker". College football uses a form of that, with each possession starting on the 25 yard line. Many state high school associations use it, though usually starting at the 10, 15 or 20 yard line.
The CFL uses it, starting at the 35 yard line (because a punt can be used to score a single point).
No game clock is used for this, just a play clock.
One of the interesting ways to use this tiebreaker is to resolve standing ties. My high school one year ended the season in a 4-way tie for our district top seed. So we hosted a 4-team Kansas-City-Tiebreaker tournament where the 4 teams played two semifinals and then a title match using this format. It was a pretty massive, epic prep football extravaganza, with fans from all four teams there.
The main complaint about this format is that, because it is a short field, it favors some types of offense over others. A strong running game or short passing attack would thrive in it compared to a team whose strength is stretching the field with deep receivers.
