Some free draft advice for the Raiders and 49ers

The Detroit Lions are on the clock, but I’m more interested in what the Raiders and 49ers are going to do in the first round of the NFL draft on Saturday.Here’s what I think they should do, starting with the Raiders, who have the No. 7 overall pick. Take the best wide receiver on the board. Not just the fastest wide receiver or the best combine workout warrior. The best wide receiver, someone who has good hands, runs good routes AND has good speed.The Raiders invested the No. 1 overall pick and countless millions of dollars on quarterback JaMarcus Russell in 2007. They’ve got to get him a marquee receiver to catch his passes. You’re already starting to hear whispers that Russell is a bust. But it’s hard to tell if he is or isn’t when the Raiders’ receiving corps is so weak. I mean, when Chaz Schilens, Johnnie Lee Higgins and, if they can stay healthy, Javon Walker and Drew Carter, are the best of the bunch, you’ve got problems.The Raiders haven’t drafted a wide receiver in the first...
