Size doesn't MATTER. It's an ADVANTAGE. Definitely, no doubt about that. Drew Brees looks all angled up when he drops back because he's making sure he can see over the line. Even his throwing motion is tailored to eliminate the fact that he's short. If Tony Romo was 2 inches shorter when he first came into the league he wouldn't be there. His motion looks quirky now but it's been refined, he used to chuck everything from below his shoulder almost.
-So there's that. Throwing Mechanics+Accuracy (hand size factored into that).
-Then the case of tucking when he's got guys open. He has the Arm Strength to make every pass in the NFL, for sure. And I don't think he really runs because he wants the attention. I think after Mike Vick everyone has finally realized that, in the NFL, no one is Fast enough and no one is Strong enough to simply just take over a game. Everyone's a Freak. The Thing with Manziel is whether or not he will be able to recognize defenses and be comfortable in the pocket long enough to do so. All QB's have an internal clock in their heads from the day they started playing the position. Running QB's grow up with that clock shorter because they know they have the ability to run away. Immobile QB's are forced to stay put, stay calm even when feeling pressure, read and pass as they are getting clobbered. It's much more difficult to get hit in the pocket and pass where you can't see where pressure is coming from, than it is to scramble and throw as you get hit by someone who is right in front of you. Like the guy said earlier, Wilson is so good because he is UNNATURALLY cool and confident under pressure. Nothing phases that dude. You can't scout that.
-Simply put we're just going to have to see if he likes to get hit. QB's gotta be a little off in the heads. Tom Brady gets lit up by Ray Lewis and he comes up hootin' and hollerin' like he just got his rocks off at a strip club. Manziel can take the hit, he's a tough dude, but does he love doin' it?
-Probably the most important thing is how much time he's willing to invest in Film study and Coverage recognition. Peyton Manning is Peyton Manning because he has computer programming software lodged into his brain. That man recognizes coverage faster than the blink of an eye. His ability to absorb defensive information from film study/experience, retain it, and regurgitate it back onto the field of play is equal to none. Most if not all pro athletes have a significant, SIGNIFICANT amount of work ethic compared to people like us. Even when people question Clowney's work habits, they are still wayyyy beyond any of ours (in the physical sense anyway) It's the one's who have that sickening, maddening type of work ethic that are a cut above. The one's that are so obsessed they literally can't sleep or even get through a normal day without doing something to progress their ability. Going back to Romo's Mechanics, great article in SI said he would spend 2-3 hours before and after practice throwing to receivers. After that he couldn't sit still for more than an hour or two at home before he was out throwing again. He spent 6-8 hours a day simply throwing a football. Sounds like a mental disability to me lol, but that's why an undrafted free agent from an unheard of D1AA college can lead that pathetic excuse for a Professional Athletic Organization known as the Dallas Cowboys to 4th in PPG.
P.S. Just want everyone on here to remember what I'm about to say here so I can get bragging rights next year
There isn't a Quarterback in this draft that is going to make a significant impact in the NFL. Maybe in a few years one of them will learn how to win some games, but no Elite QB's in this draft. Probably not even a Pro-Bowler.
