Sounds like we agree on both systems. Here's my previous post:
I've been saying for years that the NFL should sort of combine the 2 OT formats.
I hate that in the NFL a 60 minute game can come down to a coin toss, a few 1st downs, and a FG, without the other team ever having the ball.
I think the NFL should keep their same exact system but make 1 change. Make it a rule that each team gets a least 1 possession in OT. If the team that has the 1st possession scores a FG or a TD, the other team would have one possession to either win or tie. If the team that has the 1st possession doesn't score, the other team takes over and it's now sudden death. If both teams tie on their 1st possessions, it's now sudden death. If the team that has the 1st possession scores a TD, the other team must score a TD for the game to continue. I just think it isn't fair for the team that loses the coin toss to sometimes not even touch the ball in OT. This way the coin toss can't decide the game.
I think the college OT system is a joke for one reason. I think giving the teams the ball already in FG range is stupid. If they moved the ball way back to start the OT drives I think their system would be much better. I wouldn't want this type of system in the NFL.
This system is used in the Arena League, and it works fairly well. Ties are rare, and there are many exciting plays. It would also be interesting to see the possible dynamic of a 2 pt. conversion winning or losing the game.
