Shanhan mentioned that Portis’s high salary was one of the main the reasons why the team is considering the move. Shanhan also said that the possibility of Portis’s playing time getting reduced was another reason why he’s willing to let him go now so that he test the market. He didn’t exactly close the door on the chance that Portis could return but that seems very unlikely.
It will be interesting to see if any teams will be willing to bring him in as a number two running back. We’ve seen a number of veteran running backs get pushed out of the league once they start getting up their in age.
