Retzlaff: 34/156 yds (20% of att, 24% of yds)
RBs: 177/499 yds (68% of att, 76% of yds)
Others: Vander Haar (!), Bohanon, some WRs
Calling the QB our "leading rusher" is a little misleading. Seems like we have a different RB1 almost every game. If we had a consistent RB1/RB2 it wouldn't be close.
Retzlaff is 20-25% of our running game, depending on which stat you want to use. That seems pretty reasonable to me given his skill set and the desire to use that to keep defenses honest.
