The Indianapolis Colts had a good season on the field, but they still have some improvements to make if they want to return to the AFC Championship game next season. One major weakness for the team ever since drafting Andrew Luck has been the running game.

The team thought they had done something to shore up the ground game when they traded a first round pick to the Cleveland Browns for Trent Richardson. Unfortunately for the Colts, Richardson has been an even bigger bust in Indianapolis than he was in Cleveland.

According to ESPN, Richardson and the Colts have seen their relationship progressively deteriorate. Aside from struggling on the field, Richardson also earned himself a two-game suspension just before the AFC Championship game after he missed the team's walkthrough without telling anyone.

Aside from general issues with attendance and dependability, Richardson apparently also struggled with weight issues throughout the season. Richardson suffered a hamstring injury in October, and his weight ballooned from 225 pounds to around 240 pounds.

Although he denied having any weight issues, Richardson did say during the season that he was running extra sprints after practice to improve his conditioning.

Despite no longer having to share carries with anyone after Ahmad Bradshaw suffered a season-ending injury, Richardson was unable to hold on to the starting gig, eventually ceding it to Daniel Herron.

There is speculation that the team may try to move on from Richardson this offseason, and at the very least, they will probably try to void the guarantees in his contract. When asked for comment, general manager Ryan Grigson simply referred to his season-ending news conference from a few weeks ago.

"Every situation is different," Grigson said at the time. "Every player and how we deal with them is going to be different. He'll be lumped into that conversation with guys this offseason. Where does he fit? Where is he going? Is his arrow up, down, sideways, 45-degree angle?"
