Well... That's the problem. Everyone is projecting all sorts of different people different ways. There's not one set projection.
The QB is the most important spot.
The QB with the highest upside AND highest floor, imo, is Bortles. He's big and he's strong and he's reasonably intelligent. If he maximizes his potential, I think he'll have the best and longest career of any of the QBs in this draft. BUT. I have doubts about him doing that so I'm not pushing for him at 1-1.
The two guys I would prefer are actually Garoppolo, who you can probably get at 2-1 or 3-1, or Stephen Morris, who you might be able to get as an UDFA.
Garoppolo is slightly smaller than perfect (6'2", 226#) but he's got quick feet and good vision as a passer. His release point is lower than I'd like but he does a great job of getting the ball where it needs to be. He's good in the pocket.
Stephen Morris, otoh, has a good arm and he's a pretty good athlete. As a QB, he's been inconsistent although he has been playing through injuries. He's had issues with blitz recognition. But he could be a lot better than a lot of people think.
