The inevitable "Mac is still our guy" BS has already been said, we will get yet another episode of "Corky, the Cowardly QB".
He does not have the mental makeup to be an NFL QB - poor recognition of formations and calling out the OL protection leading to jailbreak rushes, no ability to go through his progressions and spot open receivers (however rare they may be), utter panic when a rusher comes free, no innate sense of when the pocket has broken down, throwing ducks off of his back foot that have zero chance for completion, refusal to throw the ball away when a play breaks down, lack of arm strength to make tough throws into coverage or sideline throws, no running ability...what does he do well? Whenever he has had to drive for a score (prior to this ****show), have you ever felt the slightest bit of "he's going to take the team downfield and win this game"? I never have, and he's yet to prove me wrong.
Zappe had composure and didn't make any bonehead plays, threw the ball away when there was nothing there, appears to be comfortable being in the pocket, steps up to throw...I am not going to use the pre-season and the even worse incarnation of the OL as a criteria. You can see someone who has presence and is focusing versus someone who just can't keep calm and lets their adrenaline make their decisions. I saw that last year too, hence was on the Zappe bandwagon. I wanted Mac to prove me wrong, instead he's just shown I was an optimist.
