The days of a one running back system which the running back gets 30 carries are now over. Currently, running backs split carries to keep them fresh and to have a change of pace towards other teams. One team that does this very well is the Indianapolis Colts. Starting with Joseph Addai and Dominic Rhodes in 2006, the colts began to use the two-back system. They went on to win the Superbowl that year. It was very effective in keeping the two running backs fresh and healthy for the playoffs. In 2009 the Colts spent their first round pick on another running back, Donald Brown. Last week against the New York Giants, the two running backs showed what they could do when combined. On their opening drive, they accounted for 39 yards. By the end of the game, Addai and Brown had combined for 161 yards on 36 carries. They also combined for three catches for 40 yards and a touchdown. These running backs are very productive because they are well rounded. They can run, catch and block. If needed, they can line up in the receiver position and go out on a route. Having these two backs helps keep them healthy and fresh for games further into the season. The Indianapolis Colts have found success with the two-back system and firmly believe in it. This gives defenses one more thing to worry about on top of that Peyton Manning guy.
