Isn't Matt Flynn on his second team competing for the starter's spot? Why would there be an outrage.
When Tebow lost his starting job (after putting up some of the worst stats from the QB position in years), many people complained that he Never Got A Fair Shot. When Sanchez got benched last year and McElroy got the start, the same people complained that Tebow was the #2 and should have been next in line (incredibly ironic, given that Tebow got the start over Brady Quinn in nearly the exact same manner).
So where's the army of people chanting to just give Matt Flynn a chance? LSU is not exactly a tiny backwater school, so I don't buy that the influence of Gator fans is the difference.
