According to the National Football Post, Rod Woodson watched Miami's Brandon Harris and DeMarcus Van Dyke. Harris is not going to be around when the Raiders pick No. 48, and the Raiders do not need to take a DB that high.
Van Dyke on the other hand will be around in the late rounds, and he ran between 4.25 and 4.28 at the combine. I can easily see the Raiders taking this raw CB, and to be honest I would be surprised if they walked away from this draft without either Van Dyke or fellow CB speedster Buster Skrine.
*Update: Clemson's Marcus Gilchrist worked out for Woodson yesterday.
