I think it's a great idea. It prevents a team from winning a game with a field goal on the first OT possession, which is something that always felt cheap to me. The only thing I don't like is that the team that gets the ball first can still win outright with a TD. I'd like to see both teams get the ball at least once regardless of what the first team does with it.
I find it funny that coaches like Sean Payton are angry about the rule change. Payton said that it would take him ten minutes to explain the new rule to his wife. He must have a really dumb wife, or maybe he's a bad explainer. Any idiot can understand the rule in ten seconds. Coaches are so detached from reality sometimes.
