Updated NFL draft boards, rankings

ESPN NFL draft experts Todd McShay and Mel Kiper Jr. have updated their draft boards and player rankings as we get closer to the big event.

There is only one major change to report. Syracuse defensive end Chandler Jones has moved up six spotsInsider to No. 24 on McShay's list of the Top 32 players available in the draft. McShay says, "Jones flew under the radar in 2011 but is rising after more thorough film study, and his size, strength and length give him impressive potential as a pass-rusher. "

Jones is the only Big East player on that list.

Kiper Jr. doesn't have a new mock draft out, but he updated his big boardInsider and Top 5 player rankingsInsider by position. No changes to report there. He still has UConn defensive tackle Kendall Reyes among his Top 5 at that position, and Syracuse safety Phillip Thomas in the top five as well.

McShay has one more good read to check out on the running back class, and how ball securityInsider affects the way they are evaluated. Cincinnati running back Isaiah Pead is included.
