I think the better question is who does fit CLK's system.
BJ and Stephens are "pro".....not professional....."style" qb's. They may work better in the new scheme than they did in last years misary. Creer seems to fit in well. Speed, decent hands, and can (sometimes) run between the tackles. Hardesty will get alot of inside carries.
My big question is with the WR's. How many 6'4" slot guys do we have like he had at USC? My opinion on Marlon Brown is well documented (overated as a gamebreaker) but would fit CLK's system. What about Jones/Moore? Can they fit into a Steve Smith role. Smaller, but fast enough to be that guy? They don't have his hands.
