If the Raiders need depth at wide receiver, you'd think they'd seek out a veteran to mentor the young pass catchers already on their roster, right?Probably, but that did not keep them from kicking the tires on former Baylor wideout Josh Gordon at his Pro Day in Houston on Tuesday as one of 21 NFL teams in attendance before Thursday's supplemental draft.At first glance, Gordon does not fit the Raiders' needs at all, what with his only having one year of starting experience.But the 6-foot-3, 224-pound Gordon, who has run the 40-yard dash in 4.50 seconds, is an intriguing prospect after catching 42 passes for 714 yards and seven touchdowns as a sophomore in 2010 before being suspended by Baylor last year after failing a drug test, reportedly for marijuana, transferring to Utah and applying for the NFL's supplemental draft without playing a down for the Utes. Two years ago, he was considered a rising star with second-round talent. Now? Many see him falling to the fourth or fifth round."The supplemental draft isn't the way you want to go into the NFL when you're growing up, but considering my circumstances, I've got to attack it with a full head of steam and do the best I can," Gordon told the Houston Chronicle. "Having a chance to play in the NFL is a dream come true for me and my family. I appreciate having this opportunity. If I'm not drafted, I'll be happy to get a chance as a free agent."The Raiders maintain their first-round draft pick from the Carson Palmer trade but are without a second-rounder as a result of the deal.And after using a third-rounder on quarterback Terrelle Pryor in last year's supplemental draft, it's hard to see Oakland doing the same two years in a row, even with a new regime.Besides, the Raiders have a potentially potent receiving corps in Darrius Heyward-Bey, Denarius Moore, Jacoby Ford, Juron Criner, Rod Streater and Louis Murphy, not counting Eddie McGee and Duke Calhoun.
