I don't see the lack of burst or top end speed. To me he looks pretty much the same. Except he looks less engaged. But he is kind of aloof so its hard to know whether he has an issue with his diminished role.
I'm also having a bit of an issue with the lack of play action but hard to argue with 27 and 30 points scored. Still feel like the offense is looking for its identity.
FWIW I hate seeing him in commercials. I'm sure its no big deal but it just kind feel like that kind of stuff, no matter when its filmed, etc. is a distraction. I've just never been a fan of it but I've no proof that it is detrimental. I guess I don't want to believe that these guys do anything else other than football, eat and sleep. lol
