KFFL.com's fantasy football rankings are fluid from week to week - and even on a daily basis if news dictates such. To keep you in the loop, our long-standing NFL Grapevine series has a new moniker and fresh look, but the flavor remains as tasty as ever. Track the changes in a snapshot approach by using KFFL's Fantasy Football Rankings Report, released at least once each week throughout the draft season.

Players on the rise

Percy Harvin, wide receiver, Minnesota Vikings

Harvin: Movin' on up

Reason: The release of wideout Bobby Wade has essentially solidified Harvin's role as the third receiver. Dynamic and explosive, Harvin is likely to be worked into the offense with a lot of screen passes and handoffs. His fantasy value is that of a No. 4, but he may be frustrating to play most weeks due to an expected erratic amount of targets.

Malcolm Kelly, wide receiver, Washington Redskins

Reason: The Redskins officially promoted Kelly to the No. 2 job opposite Santana Moss this week. The second-year receiver has sticky hands but lacks speed and elusiveness. Enough balls should come Kelly's way to make him a No. 5 fantasy receiver with the upside to be a weekly contributor.

Players on the decline

Antwaan Randle El, wide receiver, Washington Redskins

Reason: Randle El has lost his starting job to Malcolm Kelly and will be moved into the slot, which best suits his skill set. Expect a sharp decrease in looks, but Randle El didn't have fantasy value to speak of before the downgrade anyway. Avoid him in all formats. 

Bobby Wade, wide receiver, Free Agent

Reason: In what was a somewhat surprising move, the Vikes released Wade. To replace him, Minnesota brought in free-agent wideout Greg Lewis (New England Patriots). Wade was removed from our rankings and continues to have no fantasy value.

Entering rankings/unchanged newsmaker

Greg Lewis, wide receiver, Minnesota Vikings

Reason: As you may remember, Lewis played under then-offensive coordinator and current Vikings head coach Brad Childress. It should be a relatively seamless transition for the newcomer, but he isn't expected to be anything more than the fourth receiver. Fantasy owners can look elsewhere.
