I agree...this was the difference between Big Ben and JP in their rookie season...Big Ben was elusive and made ccurate throws that didn't require his OL to block all day for him. On the flip side for both JP and Trent Edwards, the line needed to protect them if they had to connect.
The other aspect I see with Josh is his "anticipation". Something Tyrod could never do. A Offensive game plan like the Patriots is pre-determined on QB's anticipation of where a receiver is going to be and to throw before that...Tyrod refused to do that so many times.
