Offensive Line...To me this is not fixable without coaching change

There has been much said as to main problem of LSU ranging from Nuss, coaches, running game, offensive line,etc. It seems crystal clear if LSU had an average OL performance we would have won the ON game and would be a playoff contender. To me this is not fixable without coaching change as the athletes are of a sufficient caliber to be performing at a much, much higher level.
