What about both college and pro going to a regular "5th quarter" where they play it as if it is a regular quarter. One team kicks off, and then play it normally. If that team scores, they kick off and the other team has one possession to tie it going the length of the field. If you score and get one stop (using the entire field, not just 25 yards), you win. This way both teams got a shot, and also it would not inflate the scores/stats of the game.
NFL overtime is fine the way it is. It's not like if you lose the toss you aren't allowed top play defense, and I think they showed a stat last night where teams that won the toss didn't win the game that much more than teams that lost the toss, I'm pretty sure it was something close to 7-6. Someone brought up playing a whole new quarter, but I don't think that's reasonable. That's 1/4 of the game where even basketball uses 1/8 of the game in a much less taxing and injury prone game.
Frankly I'm not a huge fan of either method. Though I haven't SEEN it happen, with the college method, teams could go into several OT's. But seems like in the NFL, whoever wins the toss has a huge advantage and likely wins the game.
Maybe the kickers should just kick field goals...heh.
I think, at least in the NFL, they should play a full fifth quarter. Then something else if the game is still tied.
