Yeah but he was and a true 1.000 at that for a reason. To quote Jim Harbaugh, if a worm had lasers, birds would be afraid of them.
On a serious note, Quinn has showed flashes of brilliance, seems to have trouble with one particular type of defense (3-3-5 flyover/drop 8s) and has excelled at times and has shown rare decisiveness and the ability to thread the intermediate throw in tight windows few other QBs have shown the willingness or ability to do. I think that given an offseason with Sark (are we seriously trying to pretend the man who has probably the best active resume for QB development or at the very least top 5, has somehow lucked into all of them?) that a lot of these issues can and will be fixed. If the man couldn't handle any defenses, got abused whether in man or zone, whether it was an all-out blitz or drop 8, and didn't show the flashes he did, I could understand giving him the Card treatment. But that simply isn't the case.
