First, I think someone (other than me) should create a poll so we can generate a ongoing rating across the board for the overall stats / perceptions of these two. Maybe even one for RB's & WR's, so we can see how the players stack up against each other.
SJ said on the 10pm news that he has a 'much better understanding' of the offense now. Obviously he is biased, but I took it for his word, and he seemed much more confident, not to mention much more open to talk to the media too.
I think Messinghams more simplified playbook and emphasis on teaching will help both QBs.
