That's just a good FB getting lower than the guy he's blocking. Weight is irrelevant when you have that good of leverage.
Tyler needs to get his ass closer to the ground. The NT has to have amazing base strength. Basically built like a pyramid. Tyler's problem is that he's an inverted pyramid. The guy can bench press a Sherman tank, but he carries his weight to high. He can use his strength to his advantage in the middle if he keeps his ass down and works on his balance.
