Mailbag: How good can Oakland's offense be?

Monday mail call:

Thomas from Portland wants to know how good I think Oakland can be on offense.

Bill Williamson: If it is healthy, I think it can be dangerous. The keys are the health of Darren McFadden, quarterback Carson Palmer's accuracy, the development of the receivers and the offensive line adjusting well to the zone-blocking scheme. I think all of those things are possible. I think this team can routinely score 27-30 points a game

Dennis from Kansas City wants to know if I think Tony Gonzalez will retire as a Chief.

BW: Gonzalez, who spent his first 12 NFL season with the Chiefs, has indicated he is likely going to retire after this season. The Chiefs traded the record-breaking tight end to the Falcons three years ago. I could easily see Gonzalez going back to Kansas City to sign and then immediately retire as a Chief a la LaDainian Tomlinson in San Diego. Gonzalez will always be an icon in Kansas City. I think it would be the right thing to do. He will be remembered as a Chief, not a Falcon.

Parker Keegan from Seattle wants to know if I think the Raiders could ever move running back Darren McFadden to receiver to help extend his career.

BW: I’d be surprised if that happens. He is running back and he will remain a running back until he can longer play. I’d be surprised if he ever made that switch. I like the idea, but McFadden is a running back.
