Not a bad deal for both teams. The Browns figure go trade Richardson while his value is still high, and the Colts now will split the carries between Bradshaw (who is injury prone) and Richardson. The Colts lost their top RB and TE for the season so they had to do something. Unfortunatly its not good for Donald Brown.
It all depends on how well the Browns draft is the question. Tanking only works in the NBA. The Browns I hear will be signing Willis Mcgahee, I dont really understand that wouldnt he want to join a team thats a superbowl contender and not a team in rebuild mode.
