The Colts made headlines by trading for running back Trent Richardson earlier this season. Veteran Donald Brown has been more productive.
Richardson, the starter, has 96 carries for 272 yards and has caught 12 passes for 116 yards in eight games since the trade. Brown, the backup, has rushed 48 times for 293 yards and caught 15 passes for 153 yards in the same span.
Brown looks to keep his hot streak going when the Colts travel to play the Arizona Cardinals on Sunday.
Brown, the Colts' first-round draft pick in 2009, has stuck on the roster, but he has never been able to maintain a role as the team's featured back. The Colts coaching staff likes the 1-2 punch and doesn't plan to adjust the rotation.
