The Colts promoted rookie RB Kerwynn Williams from the practice squad Friday after placing RB Vick Ballard on IR. It's an interesting move, because Williams adds quicks that no other Indy back possesses. He averaged 6.6 yards per carry and 13.6 yards per reception over 4 years at Utah State. That included a senior season with a 218-1,512-15 rushing line and 45 catches for 697 yards (15.5-yard average) and 5 TDs. Williams will begin 3rd on the RB depth chart behind Ahmad Bradshaw and Donald Brown but could factor into the return game right away. Keep his name in mind if you play in a deep league. Bradshaw's bad feet and Brown's being bad at football could make the rookie relevant to your fantasy team at some point.
