Bortles nearly led his team to a Super Bowl. He has sustained success at the NFL level as a starter, albeit with periods of struggles as well. He was very well regarded coming out of college, to the point that he was selected 3rd overall. He has good physical tools - he's big, he can scramble, etc. He's still pretty young. Why would you not want him as a backup QB? He's about as good as you can get at the position IMO. It usually isn't realistic to hold two QBs that are good-to-great starters. It's too much cap commitment at the position given what QBs go for. I'm all on the Bortles bandwagon. No matter what happens, I think he'll be an upgrade on what we currently have in Mannion.
My only concern is how much Bortles will cost. I still view him favourably. He does have warts. But I always thought he'd be out of our price range, even despite those...
