Blank will bend to the fans, and as anyone knows fans in the NFL can turn on a dime. If Vick keeps fumbling, throwing INTS, and starts losing the majority of games because he can't pass Atlanta will turn on him.
I would disagree to a degree. The Falcons could go 5-11 with Vick as the starter this year, but still the vast majority of Falcon fans will still love him to no end.
Sure, Vick losing will have a sizable contingent of Falcon fans turn on him. But it's going to take at least 2 losing seasons before you could see a majority of folks clamoring for the Falcons to get rid of him.
I would say that between 25-30% of Falcon fans, Vick really can do no wrong in their eyes. His success thus far has merited him an infinite number of chances over the next decade with this team.
For others, they are a little wishy washy, in that it would take several
years before they started calling for Vick's head. They'd be vocal about his need to improve, but probably wouldn't be openly calling for it. I would say this group makes up the majority of fans, which is about 40-50%.
For a few, they are already beginning to sour on Vick. They don't want to replace him yet, but it's not going to take much for them to want to. Another year of missing the playoffs will probably seal the deal for these folks. This is probably about 15-25% of fans.
The other portion (about 5-10%) already are very vocal about getting rid of Vick. They already want him gone.
I think if McKay is still with the team, then the chances of moving Vick is relatively decent. If McKay is gone, then I doubt Blank pulls the trigger for those marketability reasons.
Vick is the first superstar for this franchise. Sure, guys like Andre Rison, Deion, Jamal, and Brooking have been marketable players, but none are genuine superstar status like that of a Tom Brady, Peyton Manning, Barry Sanders, etc.
I think if Blank defers to a football GM like a McKay, then Vick is potentially expendable. However, if Blank is top dawg and without a presence like a McKay in the front office, and thus has his hands deeper in football decisions, then I would say that it's up in the air if Vick is ever dumped.
But again, this is all speculation, as we're all talking more about a worse-case scenario than a likely one.
