The Raiders are still in much need of drafting a top flight wide receiver. The recent addition of Michael Crabtree does nothing to change that. There are some good ones in this draft and it looks to be a pretty deep class as well. To best ensure they get their new number one receiver, taking one at number four overall would be the way to go. If they opt to go in another direction that high in the draft, there will still be some decent options later on as well.
Here are the receivers who I see showing up on the Raiders draft radar.
