15 to 20 pounds! That'll put him at at 330-335 pounds....he'll get bullied at that light weight! Really, I think you have it right on that. Tough to bull rush a 335 pound beast like Glenn.
I think this kid has got the stuff to be a tremendous LT. He's huge but agile and has 6-feet of arms to push speed rushers off trajectory. We are going to have a huge and nasty O'line for years to come
