They can be bigger than an NFL line and that still don't mean ****....Actually there's not. That's my point. LSU's O line average over 6'4" and over 323#s. That's slightly bigger than the average NFL line.
Look how big UGA's line was last year......they sucked at run blocking. An NFL D-Line would eat LSU's O-Line for lunch. Your boy Burrow would be in the hospital.
