Yep. You're describing that "athletic" thing that the youtube film guy was talking about earlier in the thread. It's interesting that you say he's "beaten" by physics, when there's guys that are (basically) Stroh's size all over the NFL. Their genetics and/or baseline athleticism "beats" physics right back. NFL O linemen are routinely 6'5 - 6'7, but, very few of them are unable to squat down and play/move from that squat position. If he can't do it, it's not necessarily something that can be learned at this age, imo. It is much easier to move a 6'0, 250 lb high school defensive tackle than a 6'3 - 300 lb *athletic* defensive lineman that has the strength and quickness to avoid his hands and rip through a shoulder. Being able to move your feet, while holding strength in the legs, is absolutely crucial. I'm not sure all the potential in the world is there. He's like a baseball player with 2/5 tools. He has *some* potential, but not sure it's enough. He needs flexibility (is the body able to squat down and stay there?), and athleticism (can he do so quickly and powerfully?). Being big is a baseline. I'd gladly take a 6'3" guard if he could stop the man in front of him.
