I'm 6'3" 245lbs. I got the size. I could run a 5.0 40. That means I'm faster than Schaub. I can throw a Nerf football 60+ yards. My wife is hot (not posting pics, though). I'm fairly smart. I watch a TON of games. I think I've got a chance to go in the third round or so. O'Brien, you reading?!?!
I could make a more accurate assessment of your draft stock with pics of wife. And also, according to ESPN, there's a very likely chance that you could actually be under 6'0 despite listing yourself at 6'3.
You move around that kind of weight without sufficient muscle memory to move efficiently or regular enough conditioning to have muscle definition, you'll get respiratory events, joint and lower back pain before you know it. I bet your throwing shoulder and clavicle would ache like a mother.
You seem like you might not have a fully developed 'lower body'. Again, we all still need the wife pics to make a better assessment of where you come in on the draft board.
