Johnny Manziel (probably in the 2016 draft). He's 6'1", 200 lbs. He's got Tebow level intensity but can actually throw a pretty pass and knows how to thread the needle into tight coverage. His footwork is actually quite good for a RS Freshman, and his arm mechanics seem just fine. Watching him today, he kind of reminded me of a mix between Russell Wilson and Tony Romo.
But- 6'1" QBs are almost never taken early, especially those who are just 200 lbs and play in a spread offense.
I need to see more before I'm sure, but Manziel looks legit to me- especially for a first year starter. He's a much better QB than his predecessor, who just went #8 overall in the last draft. Will size haunt him on draft day? Probably. Let's see if Russell Wilson changes the tide because there are a lot of good short QBs coming out in the next couple years.
