49ers looking for No. 2 WR

In Michael Crabtree, the San Francisco 49ers have a wide receiver to whom QB Colin Kaepernick likes to throw. But you may have noticed something during the Super Bowl: Kaepernick's final three passes were all sent in Crabtree's direction, which is not surprising considering the Niners did not have another WR with more than 42 catches during the regular season.
