The loss of Michael Crabtree raises a series of questions:
1. Are the 49ers deep enough at wide receiver without Crabtree?
2. Who will step up while Crabtree’s out?
3. Will the 49ers sign or trade for another wide receiver?
4. Does Crabtree’s injury affect the 49ers’ Super Bowl chances? What about their playoffs chances?
5. Are the 49ers still the favorite to win the NFC West?
