They should adopt that format anyway, it's much more exciting and more fair to boot.
What’s “fair” about a defense that keeps its opponent bottled up in their own end all day being “rewarded” in OT by giving the opponent the ball in field goal range?
The one thing I don’t like about NCAA overtime rules is that almost all OT games end with very high scores that don’t accurately reflect the offensive/defensive capabilities of the teams. And aren’t the players’ personal statistics skewed by overtime, too?
