You can't say the O Line under Franklin has been effective. Football is a simple game. You have block, tackle and execute. It's situational, not brain surgery. I am not suggesting we return to three yards and a cloud of dust but our line at the average of 6' 5" , 300 + lbs does not know how to effectively run block. We have talented running backs who struggled this year and for many years. Michigan just showed everyone what power football is and there is no substitute for it . It wasn't until just two years ago that under Franklin that we saw a QB under center and utilized a full house back in certain situations. Football is won and lost up front. That is why we lose. Slow out of sync weak run blockers. Balance on both sides and we don't have it.
