I haven't read thru the entire thread so if this point has been discussed, I apologize. But IMHO, the one limiting factor that I fear the most is: Jim Harbaugh. Here's why. Our defense will take it's lumps at least the first half of the season due to:
1. No Bowman until the midway point.
2. Aldon being suspended
3. New secondary.
My guess is that will give up at least 7 more points per game than last season as a result. It will be our offense's responsibility to make up those 7 points if we expect to win ball games. So I think Harbaugh knows that he'll have to take Bo Schembechler football and throw it in the garbage can. We can no longer expect to win ball games by kicking field goals and winning the time of possession/field position battle. We'll need to score points.
Back to "Bo-based" football. We simply need to get rid of the over reliance on the fullback led runs between the tackles and replace those with a nice blend of multi-receiver pass patterns (much to the chagrin of Harbaugh) because we all know the definition of insanity which is "doing the same thing over and over again and expecting different results."
But we have no choice. Our offense MUST carry the torch this year if we are to succeed.
