I got nothing
Yeah, 60% is one of the numbers quoted (in fact I found it cited in an ESPN.com article) but that sounds about right on the first-possession winners.
30% becomes 60% because there's a good chance that field position came into play after the 1st possession. Fact is the 60% figure is more important and more telling than the 30%, regardless of which possession won the game.
To be clear though I am not arguing in favor of the new OT rules, just saying the above does nothing to defend the prior OT rules.
