re: Marcus Davenport

The back breaker wasn't a sack (if it's the one I'm thinking of; maybe he had two of those though). That's the one Sean challenged as they ruled it a pass instead of a fumble.

The strip play where the ball shot up should be a sack.

Edit:
Basically any hit that results in a pass attempt (incompletion, completion, or interception) isn't a sack.

Any "hit" on a QB that results in a fumble is a sack. Doesn't matter if he only hits the ball or the QBs hand.

So unless he had two back breaker hits, he only had one sack.

They keep each other fresh
