The Colts reached an agreement Saturday with first-round pick Joseph Addai, a running back who they hope will fill the shoes of departed starter Edgerrin James. The five-year contract includes $4.7 million in guarantees and a maximum value of $11.165 million. Agent Ian Greengross confirmed the deal, which Addai is expected to sign Sunday. The Colts are scheduled to report for training camp Sunday and begin practice Monday.
