The Facts: In crossing the bay, Crabtree has gone from third option to potential superstar. Vic Tafur of the San Francisco Chronicle writes that the former 49er has been the early “star” of camp for the Raiders.

Diehards Line:As PFT's Mike Florio suggests, there's a long way to go until Crabtree becomes a star during games that count. Drops and limited opportunities punctuated his last season in San Francisco, which ended with 68 catches for 698 yards. In six seasons with the 49ers, the 2009 top-10 pick had only one 1,000 yard receiving season, cracking the barrier with 1,105 in 2012. Once he became a free agent, Crabtree generated little interest, eventually signing a one-year, $3.2 million contract with the Raiders, who also drafted Amari Cooper in the first round of this year's draft. While hopes are for Cooper, Crabtree would provide huge value if he can get his career on track. It's worth watching.
