Stylistically, he's Brett Favre. At least thats what he looks like to me. He wants to make a play every down, and sometimes it comes through in spades and others it's the ugliest thing you have ever seen a QB do.
He's got time on his side. This isn't Weeden where if he doesn't pan out in a year or two he is totally done. He needs some time on the bench, and on the practice field to rework his mechanics. His ability to make awkward throws and get completions out of them is impressive, but sometimes when his balance is off, you'll get quackers like you did last night on that throw to Benjamin.
He's getting there. I believe he'll eventually get there. It looks like he knows where to go with the ball now, which is a huge improvement from game 2 and a step up from game 3. Now he has to work on getting better in the pocket, stepping up and into his throws. He's got the talent, it's all right there for him.
I think we could effectively make him a starter if we absolutely need to, but I'm glad the Browns chose Hoyer to start. You can clearly see that Hoyer is miles ahead of Manziel in the pocket, and at the end of the day that's where you need your QB to make plays.
