I think the biggest addition to our offense will be Boldin. Ultimately, it comes down to losing Walker and getting Boldin. We did not have a real #2 receiver last year. Even when Manningham was healthy, he was solid but nothing special. Boldin is somebody you really have to account for, or he'll eat you alive. They can't double Crab, Boldin, and Vernon. At least one of those guys will get single coverage, and since there isn't a linebacker in the league who can run with Vernon downfield, my guess is that Boldin will see some single.
