What impresses me most with the offense is Bennett's emergence and our using him more often. We already know what Roy is, and we certainly know what TO and Witten are. Throw in Bennett, if he develops like he looks to be, and the offense becomes even more unreal.
Also, to note on Williams: Anyone see ESPN spotlight his two blocks on the "win-sealing" play where Barber dove for the first down? Roy blocked one man and took him out of the play, and then moved upfield and blocked the other guy that most certainly would have stopped Barber short of the 1st.
