If you want to take the QB runs out, then also take into consideration we were down to our 4th string RB who weighed a whopping 185 lbs wet. Also throw in injuries on the entire left side and center.
I am not saying Raiola is a world beater coach but you are picking and choosing how you want to decide if he is or isn't any good.
Do you think he is an upgrade over Austin? I saw what Austin was doing and teaching and didn't like it, note the players comments about the differences. Raiola seems to have a good relationship with his players and it sounds like he is getting input from other/outside coaches so he himself is coachable.
