Amari Cooper (Wide Receiver): The Raiders are hoping Cooper can become a franchise wide receiver, and so far he has shown just that. Cooper made Patrick Peterson look silly in preseason blowing past him for a completion which leads me to believe that he is the real deal. Cooper will be an offense that is very reliant on the pass so he should see WR1 level targets almost immediately. As a rookie what he does with those targets is all up for interpretation, but expect him to put up some serious fantasy points.
Michael Crabtree (Wide Receiver): Crabtree was brought in to be a big free agent however his play does not suggest he is. Crabtree was average with the 49ers however how Crabtree produces in this passing game could say a lot about the two quarterbacks he has played with (Carr and Kaepernick). Crabtree is a late round pick at best.
Mychal Rivera (Tight End): Rivera will be the Raiders number TE1 and should get a large number of targets. Rivera outplayed the tight ends on the Raiders roster to earn this spot so it will be interesting to see if he can be productive.
Latavius Murray (Running back): Murray is one of the favorites for fantasy owners in this offense and for a good reason. Murray is an explosive back with a lot of upside. He routinely makes defenders miss and can be the workhorse running back the Raiders need. The Raiders line will have to be pretty good in order to make sure Murray does not get banged up and so far, that does not appear to be the case.
