Colts running back Trent Richardson has no excuses in 2014. He's got to improve dramatically on the 2.9 yards per carry he averaged after being traded from Cleveland to Indianapolis.

To that end, Richardson said he plans to spend the offseason delving into the playbook. “Learn the system, not just memorizing it,” Richardson told ESPN.com. “Learning the whole concept of the system. There's a difference between having it memorized and feeling comfortable with the system.

"I’m going talk to a lot of veteran players, talk to Adrian (Peterson), talk to (LaDainian Tomlinson), talk to Emmitt Smith to make sure I’m the best I need to be next year.”
