Vick surrenders early; is it a good move?

Michael Vick is renown for his moves on the football field, but I am wondering what folks think about his latest legal move: as detailed in this New York Times article, as part of “an apparent attempt to speed his return to football, Michael Vick began serving his prison sentence Monday on federal dogfighting charges, more than three weeks before he was scheduled to be sentenced.”  This Atlanta Journal-Constitution article includes this additional information:

From the beginning, Mr. Vick has accepted responsibility for his actions and his self surrender further demonstrates that acceptance,” Billy Martin, one of Vick’s lawyers, said in a statement. “Michael wants to again apologize to everyone [who] has been hurt in this matter and he thanks all of the people who have offered him and his family prayers and support during this time.”

U.S. District Judge Henry E. Hudson of Richmond, who will sentence Vick on Dec. 10, signed an order Monday to allow the U.S. Marshal’s Service to take Vick into custody. Vick, who surrendered to authorities in Richmond, was put in custody “based solely on his desire to begin his period of incarceration prior to his sentencing hearing and not because of a violation of any condition of his bond,” Hudson wrote.

I’d be especially interested to hear from experienced federal defense attorneys about whether they think this is a good move by Vick.

UPDATE:  Experienced defense attorney Jeralyn Merritt writing here at TalkLeft does not quite understand this move by Vick.
