Who will thrive under Cam?
I think everyone - no lie and not a flame to the current staff.
QB - I love Krags (hope he gets to stay on staff as just QB coach, I really really hope so, but I wasn't able to follow this the whole day so not sure what the rumor is about what will happen with him) but Cam will be beneficial with understanding, tutoring, and play calling around the QB
RB - with the wealth of talent, I think a little more diversity (traps, leads, mis-directions, etc) and the amazing talent will get to shine more
WR - again, in conjunction with the former 2 categories, I think he will be able to put them in very good position to succeed (due to putting the D on the "defense", if you will, no pun intended). Plus, I think that they are getting coached pretty well now (I saw a definite increase in the production from start to finish of last season, and there were a ton of drops - not exactly a coaching thing, just have to catch the ball).
Defense - with the O out to a pounding and commanding lead, it lets the defense (who has obviously been stellar) stay off the field (and rest) and puts more presser on other offense
Plus, Plus, Plus, Plus IMO
