What is Darren McFadden's future?

The NFL Network reported that the Oakland Raiders checked in with running back Darren McFadden about a contract extension.

He is entering the final year of his contract that began with Oakland in 2008 when the Raiders took him with the No. 4 overall pick. The report states McFadden was not interested in an extension at the time.

I wouldn’t take that as a sign that McFadden wants to leave. I know that he has been interested in re-signing but I think he simply wants to see what he can do in his contract year -- especially now that Oakland is going back to the power-blocking scheme that best fits McFadden’s style. He struggled some last year in the zone-blocking scheme.

In another AFC West note: U-T San Diego wonders if Charlie Whitehurst will hold off rookie Brad Sorensen to be Philip Rivers’ backup. Sorensen was better than Whitehurst on Thursday night against Seattle.

Whitehurst was playing against better competition and Sorensen probably is not ready to be a backup. If Whitehurst fails throughout the preseason, the Chargers may be more apt to look for a backup quarterback elsewhere.
