Bortles will be fine as long as he doesn't go pro this year. He's already better than Locker by default cause he's atleast semi-accurate right now. If he comes out this year, I can see him turning into Gabbart if he's picked high and forced to play right away.
Otherwise, go back to school, get more comfortable actually running an offense (cause you can see that O'Leary plays it pretty safe. They're basically a run first team.), and he'll be fine. I mean, he has the tools. Just needs the confidence and knowledge, and if he's thrown to the NFL wolves, he's not getting either.
