So, we want Murray to fight for more yards, but Dez to not. Garrett has no clue what he's doing.
Dez just needs to be smart about picking his spots. Right now he's still young and hard-headed.
He thinks he can just out-muscle 5 guys at once and ends up putting himself in bad situations by trying to create something out of nothing.
If it's a critical down and late in the game and we need those yard, then by all means fight for those extra yards. However taking on 5 defenders in the middle of the field in the first half after the 1st down has already been picked up is reckless.
