The Raiders' receiver room is pretty packed. Competition will be fierce for spots behind Amari Cooper, Jordy Nelson and Martavis Bryant.
Oklahoma State alum Marcell Ateman will be fighting for a spot this offseason. The seventh-round won't be given anything, but has the tools required to compete at the professional level.
He's formally getting paid for his services now, after signing his four-year rookie contract on Wednesday afternoon.
Ateman and the Raiders rookie class joined veterans for the offseason program starting Monday, and activity increases with OTAs beginning next week.
Ryan Switzer and Dwyane Harris, who are also return men, join the receiver competition with Ateman, Seth Roberts, Griff Whalen, Johny Holton and Isaac Whitney.
Ateman isn't the fastest guy, but he's known as a quality route runner with sure hands. He had 146 receptions for 2,466 yards and 13 touchdowns in his college career.
