The San Francisco 49ers' Super Bowl hopes took a major hit when wide receiver Michael Crabtree went down with a torn Achilles tendon during organized team activities. The star wideout is expected to be for most or all of the 2013 season.
Did the team's Super Bowl hopes go down with Crabtree? Aaron Nagler and I debate just how big this injury is for the NFC favorites. Will the injury to Colin Kaepernick's favorite target end the 49ers' two-year run of dominance?
Who will step up to replace Michael Crabtree, and can Jim Harbaugh and Co. coach this team through his recovery time?
