I found it very telling how Stew responded to the read option question. He said something to the effect that it was a sensitive subject, before going on to say that he preferred more traditional running sets.
That tells me one of two things: either Chud wants to use it more than the backs would like, or, perhaps Cam has pushed hard for it's use. In either case, it hints at a bit of discord. Someday perhaps we'll have a better idea of why we insisted on using it so much early in the season.
I doubt that considering he's looked pretty good under center and has proven he can play well in a pro style offense, remember that he doesn't call the plays... And plus we can't forget that incident with cam's comments after the cowboys game about chud.
