Just bear in mind that one simple switch of coaching might be the kicker he needs. Not saying it would work but for a late round pick (and with the ability to switch him to another position) it's well worth it. He has perfect tools.
As an aside, I was watching Derek Carr and trying to put myself in the mindset of a QB needy team. I have no idea why a team would select him over trading for Ryan Mallett. Carr just lacks that leadership vibe which I think Mallett has developed.
Oh and Teddy Bridgewater is calmer than the Dalai Lama. Love that guy. No way I'd take Bortles or Manziel over him.
