Mailbag: Could Branden Albert still be traded?

Weekend mail call:

Jonathan Coleman from Smithville, Mo., wants to know if I think the Chiefs could trade left tackle Branden Albert to Green Bay because of the season-ending injury to Bryan Bulaga.

Bill Williamson: I think that ship has sailed. The Chiefs are happy with Albert and now that training camp is in full swing, the Chiefs are totally intent on keeping Albert, for this year, at least. Plus, rookie Eric Fisher is focused on playing right tackle. It would be counterproductive to move him with the season so close.

Hunter from San Diego wants to know what I think Philip Rivers' job security is like with the Chargers.

BW: I think we will have our answer after this season. The new brass wants to see him improve and it thinks he can. If Rivers, 31, has takes another step back, I think the Chargers will start to think about the future. I think he will be the quarterback in San Diego in 2014 regardless, but San Diego is not going to wait too long for Rivers to get it together.

Mike MacPherson from Ottawa, Canada, wants to know if I think Oakland quarterback Terrelle Pryor has improved this summer.

BW: Yes, Pryor has shown some improvement as a passer at times. But he also has some moments that frustrate the Oakland coaching staff. He remains a total work in progress as a quarterback.
