McNabb is going to be confused again...or should we say "still"?
I do like the new proposals of score a TD or the other team gets a chance. It's closer to an ideal system. The college system can go on too long and it's more like a shootout in hockey than an OT because of the short distance needed to score. A lot of NFL overtimes are won by FGs, some even kicked on 1st-3rd downs to just get the game over with instead of using all downs and trying to score a TD. So, if the offense doesn't score a TD, I like giving the other team a chance. It's debatable if the other team should get a try after a TD on the opening OT drive, but if the first team was able to go all the way down the field to score a TD, they earned the win far more than a team that got maybe 2 first downs and a penalty to hit a FG.
I hope it passes. I guess the '2010 postseason' rule is going to make it a test, like MLB and instant replay experiments in the postseason. I believe it would be better to test something like this during the regular season for a few reasons: less chance of a bad rule costing teams in the playoffs...and it's very easy to have a postseason with no overtime games, even one or two is a small sample to test the effectiveness of a new rule or experimental rule.
