Honestly, I think that's the only way he doesn't have a good career. I feel the kid has all the tools needed to be a good to great NFL QB, but if he can't get the protection he needs to learn it's over.There's the very real danger that even if Mariota was NFL worthy getting his shot on a team with lots of suspect pieces around him and something less than an established staff/system that his career could still end up in the drink over faults not his own.
