If the Ravens don't re-sign recently released Derrick Mason, here's the top 10 unrestricted free-agent wide receivers:1. Santonio Holmes, N.Y. Jets: Clutch receiver who is dangerous after the catch. Has consistently tormented the Ravens' secondary.2. Sidney Rice, Minnesota: Prototypical deep-threat ... when healthy. Missed first 10 games last season.3. Steve Smith, N.Y. Giants: Excellent route-runner who steps up on third downs. But knee surgery could force him to start season on PUP.4. Braylon Edwards, N.Y. Jets: Potential to be a top-tier No. 1 receiver has always been stunted by inconsistent hands. He can make the unbelievable catch and drop the easy throws.5. Malcom Floyd, San Diego: Some would argue this is too high on the list for Floyd. But he's a 6-5 receiver who has averaged 17.3 yards per catch for his career.6. Plaxico Burress, N.Y. Giants7. Randy Moss, Tennessee8. Lance Moore, New Orleans9. Mike Sims-Walker, Jacksonville10. James Jones, Green BayNote: Carolina's Steve Smith, who reportedly wants to play for the Ravens or San Diego, is under contract for two more seasons. The Ravens would have to trade to acquire him.For the latest Ravens news, follow Jamison Hensley on Twitter.
