McGahee passed his physical today and is good to go for a team that had an enormous hole at running back after Richardson (the only running back who got a single carry for them this season) was traded.
McGahee has been out of work since the Broncos cut him over the summer. McGahee ran for 731 yards on 167 carries and had four touchdowns in Denver last season.
The Browns also have Chris Ogbonnaya and Bobby Rainey on the depth chart, but assuming McGahee is in good shape and can quickly pick up the playbook, McGahee would seem to be the likely No. 1 running back going forward.
