Funny thing is -- everyone bats 1000 in hindsight!
As far as "developmental," every QB coming out of college is
essentially developmental -- and the degree of difficulty directly
relates to the system the kid is placed in.
Everyone knows the system Miami is running is probably (next
to the Cheats) the most challenging/demanding on the QB in the
league.
If someone can't see, or refuses to acknowledge the obvious positive
aspects and developments in Rosen's game then... I would assume that's
clearly an expression of personal bias.
In my view, Rosen has ALL the core ingredients to be a efficient, high
performance (consistent) NFL QB. The raw material is there. He's already
getting the ball out faster -- and shows signs of really understanding what
he's facing and how to best execute. But no doubt -- he's got a ways to go...
I honesty believe the real question at this point is how much more positive
growth can Rosen achieve? Is he near maxed out? Or can he get better
reading the D, making quick and correct decisions, refine his bag of
tricks like looking off etc., and improve his overall accuracy (right now
IMO he's much more proficient in the vertical vs. horizontal plane
hitting moving targets).
Every player has a ceiling. I think Rosen still has significant upside.
The question is will he be able to fully develop to his greatest potential?
Or, like so many QBs, hit a wall he can't get past?
