AFC West mailbag

Midweek mail call:

David Coleman from Buckeye, AZ wants to know if the Chargers packaged their two top pick (No. 28 and No. 40) for a running back, who their top choice would be.

Bill Williamson: If San Diego made that move, it could probably get to the 12-15 range. Clemson’s C.J. Spiller is the premier back in a stacked running back class. San Francisco is said to covet him. The 49ers pick No. 13 and No. 17. If the Chargers wanted to take a crack at Spiller, they may have to get the No. 12 pick from Miami. Because the Chargers have other needs and because the running back group is so strong, I’m not sure San Diego would make such a move.

Mike from Maryville, Mo. wants to know if Kansas City could trade a second-round pick to Baltimore for left tackle Jared Gaither.

BW: There has been talk Gaither could be on the move. Teams such as Washington and Dallas could make a play for him. Kansas City could use a tackle and it may use the No. 5 overall pick on one. So, pursuing Gaither could be smart. The Chiefs have two second-round picks and using one on Gaither would be a worthy investment and allow the Chiefs to both get a quality tackle and address another need, such as safety at No. 5.

Stephen from El Dorado, Arkansas wants to know my opinion of Oakland quarterback Bruce Gradkowski.

BW: I admire Gradkowski. You can’t deny the impact he had on Oakland’s offense when he replaced JaMarcus Russell last November. The unit got instantly better with Gradkowski. He is a sparkplug, whose teammates really like playing with. With that said, I think, ultimately, Gradkowski’s limitations as a pure quarterback will get in his way of being a longtime solid starter. But he is currently the best quarterback on Oakland’s roster and if the Raiders had to start the 2010 season with Gradkowski behind center, it wouldn’t be the worst thing in the world.
