Seahawks are 4 deep at RB, however Walker is the only home run type on the roster. Charbs and Martinez (who I think is great) are more the power runner type. No market for RBs especially on expiring contracts and injury prone. So as Shark said, McIntosh will likely end up on the PS and they will go with a committee at RB with Walker being the starter. Should be a really good RB corp that has the depth to handle injuries.
