Mailbag: Chargers' plan at No. 18

Weekend mail call:

Peter from NYC wants to know what I think the Chiefs think of quarterback Ricky Stanzi.

Bill Williamson: By signing Brady Quinn to be Matt Cassel’s backup, the Chiefs made it clear they don’t think Stanzi is ready to be the No. 2 quarterback; expect him to remain the No. 3 for the second consecutive season. That could change if the Chiefs pick a quarterback early in the draft. I wouldn’t be shocked if the Chiefs showed interest in Oklahoma State’s Brandon Weeden or Michigan State’s Kirk Cousins in the second round. If either of the players or drafted, Stanzi would be in trouble. But I do think he will get another year to develop.

Edward Moretti from Imperial Beach, Calif., wants to know which of these players -- Nick Perry, Harrison Smith, Luke Kuechly and David DeCastro – has the best chance of being the Chargers’ pick at No. 18?

BW: In my latest mock draft I have Illinois’ pass-rusher Whitney Mercilus going to the Chargers in the first; that area is San Diego's biggest need. If Mercilus, and the other top pass-rushers are off the board and Perry, Smith, Kuechly and DeCastro are still available, the Chargers would be in a great spot because all are terrific players. Kuechly and DeCastro would be the best value picks and Perry and Smith would fill the biggest holes. But, in that instance I think DeCastro could be the choice because of the combination of value and need.

William Denning from Atlanta wants to know if I think Denver could take Alabama cornerback Dre Kirkpatrick at No. 25.

BW: I think defensive tackle will be Denver’s biggest need and that’s where it will start. Kirkpatrick could be a backup plan and I think he will be considered. But the Broncos’ draft needs start on the defensive front.
