I much prefer the college OT but the NFL OT now is at least better than it used to be. At least now the team getting the ball has to go all the way in and score a TD to end the game rather than just having to drive to the opponent's 30 and kick a FG and claim a win. The college OT is the best system but the only thing I would change in the college system is to eliminate one point extra points from the start. If you made folks go for a 2 pointer starting at the first OT after every TD you could end a lot of games a lot quicker.
