Best of the Web. No weak links here:Brian Burke, Advanced NFL Stats, on onside kicks and expectations: With 4 minutes left in the first quarter of last week’s Cardinals-Seahawks game, Arizona’s Neil Rackers booted a short but high ‘pooch’ kick that was quickly recovered by the kicking team. The kick recovery was worth a very considerable +0.12 WP. The Cardinals went on to score a touchdown, taking a 14-0 lead.

Now, obviously, time of possession can come as a byproduct of some good things, like moving the ball and converting 3rd downs, but here he's talking about holding everything else (yards, efficiency, etc.) equal and just asking how much T.O.P. contributes to winning in and of itself.
