re: SEC O Lineman. How big is too big?

I played OL and DL in HS and DL briefly in college before getting injured and transferring to UGA. Honestly, the best OT I played against at any level was 6'5" but only about 255 lbs. he had quick feet, a long wingspan, and really good bend that allowed him to get leverage. My HS had two 6'3" 300+ pounders at the tackles and they were a liability because they were too fat and too slow. Size helps, but it doesn't mean shite without athleticism.
