Sherman Lewis, what was his effect

[CRedskinsRule]

First, if the mods want to merge this, it's all good.

I really want to ask the biggest underlying question: How much of yesterday's game, good and bad, were tied to the introduction of Sherman Lewis. Some key examples that I would cite:

Rock/Betts together in the backfield more.
DT specifically thrown at more
Shotgun at the 2 - good and bad plays out of it.

Maybe less specific but also:
more confusion in the pass pro, without Zorn in his ear did Campbell miss setting assignments

Also was the playcalling better, or just different?
It seemed to me that player execution was noticeably worse. Particularly Campbell early. and middle. and late.

So, bottom line, with the bye week here, and 2 weeks to reset this season. What did bringing Lewis in impact? Will his presence be an overall positive, negative, or I don't give an eff, throw me another beer? (Trample, I know your answer )
