In the UFR Brain pointed out that Michigan started running its own version of the Power O running game. He used the long Toussaint run as an example and then linked to a smart football article.
It seems to me from the limited amount I know about football, that it is usually the backside guard that pulls in the Power O (this was corroborated by the link he provided). In the Tousaint run, Omameh pulled but was the play side guard. What is the advantage of pulling the play side guard? Is it just that he can get to his block faster? In which case why would you not always pull the play side guard?
Let me say that I don't know too much about football, so the answer to my question may be obvious. Hopefully some of you on the board can learn me a lesson in some footbaw.
