If Reid is fired, Vick's job security becomes a little dicey. The problem is that Vick's particular style of quarterbacking is "love it or hate it" type of work. Reid has firmly backed the mobile and athletic nature of Vick. To a lesser degree he handled a mobile QB in the form of Donovan McNabb prior to the Vick era.
Reid is known as one of the best offensive minds in football and is a tremendous groomer of QB talent. He helped turn McNabb into one of the best QBs in the NFL. He turned Kevin Kolb into a $63.5 million prize for the Arizona Cardinals (what happened to him once he got there is another issue entirely.)
Can the Philadelphia Eagles win a Super Bowl with Michael Vick at QB?
Other coaches may not have the patience of Reid. They may not see the direction that the 32-year-old Vick is taking the Eagles on as a proper course. After all, Vick is clearly not getting any younger, and question marks abound as to whether or not he can ever lead a Super Bowl championship team.
Reid is a loyalist. He sticks by his guy, for better or worse. Catcalls came early and often for McNabb, but aside from a few games where he was pulled early, Reid stuck by him as the starting quarterback of Philadelphia, and he will stick by Vick as long as he can.
Do not mistake this as Vick not being capable of succeeding right now. He is still a lethal weapon that forces defenses to game-plan in unique and troublesome ways. However, he is a niche QB, a player that many other coaches may want to stay away from, and start fresh either with Nick Foles or some other young signal-caller.
Vick will be the QB of the Eagles now and tomorrow. That is, as long as Reid continues to roam the sidelines every Sunday.
