Honestly haven't followed college football enough to know they changed the rules this year, but I saw that the Illini upset Penn State in *NINE* overtimes. I was amazed that in a game with that many OT's, the final score was a paltry 20-18. Apparently, though, the NCAA changed their OT rules.
Basically, the first two overtimes have little change, with alternating possessions from the 25 yard line. The only change here is that you HAVE to go for a two point conversion starting in the second overtime (no more kicks). That was the rule starting in OT3, so it's not a huge change.
Starting in the THIRD overtime, however, there are no more drives. Basically, each team gets to attempt a two-point conversion. That's it.
I know they said they want to protect players from getting worn down or injured by really long multiple overtime games, but I really don't like this way of determining the victor. Basically, it rewards the team that has the best short yardage unit and doesn't really giev a fair test of the entire team.
