The San Francisco 49ers best wide receiver has torn his Achilles tendon, and will most likely miss at least the first 6 weeks of the season. That pretty much makes him undraftable this summer in fantasy football redraft leagues. This also makes Colin Kaepernick just slightly less valuable, as he and Crabtree really developed great chemistry last season. This boosts Anquan Boldin's value as well as Mario Manningham, should he find himself healthy enough to play on a weekly basis. Vernon Davis was pretty disappointing last season, but this could be huge in his return to fantasy greatness. Maybe even a guy like A.J. Jenkins bursts onto the scene this season. Make sure you keep an eye on the 49ers offense this offseason as they should no longer ignored in fantasy drafts!
