Speculation is mounting that Bill Parcells will return as head coach of the Cowboys. Multiple NFL sources said Parcells plans to return to work this week and may even attend some of the Senior Bowl practices, which begin this week in Mobile, Ala., for Saturday's game. Other sources said he was upset when the Seahawks gained permission to interview special teams coach Bruce DeHaven two days before his contract expired, which also lends credence to the idea that Parcells is returning. The Seahawks did not get permission through Parcells, but rather someone over him, most likely owner/general manager Jerry Jones.
