AFC West mailbag

Weekend mail call:

Tommy from San Diego wants to know if I think Philip Rivers will have a bounce-back year in 2012.

Bill Williamson: I would think so. Rivers just turned 30 and he is still in the prime of his career. He finished the season fairly strong. As long as the offensive line is competitive and the Chargers make some upgrades on offense, Rivers should be fine no matter whom his coach is.

Joe from St. Louis wants to know if I think the Chiefs will add a running back in the offseason.

BW: The talk is that Kansas City will add a bigger back to complement Jamaal Charles. Thomas Jones is not expected to be back. The Chiefs could add the back through free agency or in the draft. Charles is still the guy, but the Chiefs want to bring in a pounder to help.

AJ Prine from Victorville, Ca. wants to know what type of compensatory picks Oakland will get after the free-agent losses of Nnamdi Asomugha, Robert Gallery and Zack Miller.

BW: Compensatory picks are awarded on a complicated formula that puts several things into account. I think the Raiders, and this is just an educated guess, will get two third-round picks. The comp picks will be announced in March.
