Michael Crabtree has torn his achilles in OTA's today. ESPN is announcing the injury right now. I wonder how this will impact their chances at a return trip to the Superbowl, as he was their obvious #1 WR heading into the 2013 season. Boldin is a great possession guy, and of course Davis is a great receiving threat at TE, but Crabtree was the main man at WR for Kaepernick. One of their rookies or second year guys are going to have to step up and start in 2013. It is a tall order to expect any of them to produce at the level Crabtree did last season. I hate to see any player get injured, but it is a definite boost to the Rams chances at making up ground on the Niners sooner rather than later.
