I was talking about this on a college board earlier this week:
Since the NFL adopted OT back in 1974 the team that won the coin toss wins the game about 52% of the time. Since they moved the kickoff back 5 yards to the 30 the team that wins the coin toss ends up winning the game about 60% of the time.
There have been a few suggestions to alleviate playing for a FG.
-Teams need to win by 6 points. But that could drag things on and on. A 3 hour game can now go 4 hours or more and that would reek havoc with the TV networks.
-Guaranteeing both team one possession of the ball would be another.
- moving the kick off back up to the 35 in OT. (The idea I prefer but you can add the win by 6 points to it as well. You can also say that after 3 possesions by each team 3 points can win the game.)
I actually like the current system. If you (NFL coach) don't want to risk an overtime loss where you may not even see the ball don't play for a tie.
