Seth from New Orleans recently hit the NFC West mailbag with a question seeking clarification for recent items regarding what Michael Crabtree's injury will mean to the San Francisco 49ers. He thinks some of my analysis appeared contradictory, but I'm pretty confident we can bridge what Seth sees as a potential gap in logic.On the one hand, I suggested losing Crabtree could be significant to the division race, particularly with the Seattle Seahawks adding Percy Harvin.
