Because Cook had 5 runs for -4 yards.
But, like the Kincaid situation, that's not really Cook's fault. He's a scat back and it's crazy to me that anyone thought he could be anything else. Especially the guys that get paid millions of dollars to make these decisions.
We paid Harris and Murray and they both dress every week. Dorsey needs to learn when to use each of his RBs because he has no clue right now.
