Crabtree - Shepard?

We're excited about how Evans has been playing, but Crabtree has the same number of TD's, and only a 100 less yards on 75% of the targets. The Raiders have a lot of weapons, but Crabtree is the guy I think we have to keep contained. If Grimes has issues with that will we adapt in the secondary? possibly move Grimes and Hargreaves around? (maybe even play the Thorpe award winner we have the bench?)

Can Russell Shepard be a legit #2 WR? The Raider's secondary has issues, so a good game here doesn't necessarily answer that question affirmatively, but a bad game could be a concern and likely a loss if we aren't distributing the ball.
