Sims isn't ideal height, at 6'4 or 6'5 depending on which service you follow. But that, combined with his long arms, is more than enough to get the job done blocking on the edges. He shows good bend, and has quick feet for pass protection. He's among the higher rated OT recruits Richt has brought on board, and the physical tools are all there. He needs to continue adding weight and strength, without losing much quickness. 280s can work, as we saw with Kolton Houston this past year, but ideally you want your tackles closer to 300. Sims shows the frame that should comfortably handle that weight.
While highly rated, I wouldn't expect Sims to play immediately. He may, because our need at OT is that great, but you'd prefer he take a little time to reshape his body, add strength, and get accustomed to practicing against SEC DL before he has to play them on fall Saturdays. In time, we have a guy that could compete for top honors as an offensive tackle. He's not raw, but he does need some work, particularly physically. But we want quality OTs, and Sims definitely fits that bill with future NFL ability.
