I think Marshawn is going to be very candid in this interview.
I also believe that he will announce his retirement at the conclusion of this season during this interview, which will propel the Seahawks to a monster run and another SB win.
I could be completely wrong. But I think this would be how he chooses to announce that he's done - to his boy M-Rob.
I just think the man has had enough. He's sacrificing his long term health every week and is done with the NFL's witch hunt over his unwillingness to speak to the media.
