I didnt know there was a real questionI can decode this one....you don't have a sufficient answer.
The answer is, the offense was flowing through Speight so well that michigan didnt need to do anything fancy on offense, so peppers was used rarely on O,and on defense, as a rover LB, he lines up everywhere......every game this season has had a defensive rotation like that...he plays everywhere on D because he can do anything on defense. His base position is rover OLB and he goes where the offensive play or blitz dictates.
