When the Colts traded a first-round pick to the Browns for running back Trent Richardson in 2013, they probably didn't envision the problems that have risen from someone once considered to be a can't-miss NFL running back.
According to an ESPN report, there appears to be a lot more to Richardson's AFC Championship Game suspension than the simple fact he missed a team walkthrough without notifying the team beforehand.
The report states that multiple incidents have piled up that have frustrated the Colts. After Richardson injured his hamstring in mid-October, his weight ballooned from 225 pounds to 240. When Ahmad Bradshaw fractured his fibula against the Patriots in November, the Colts were unable to get in touch with Richardson until 1 p.m. the next day.
The tipping point was probably that missed walkthrough before the AFC Championship Game. The Colts suspended him for the conference title matchup against New England, and if he's back with Indianapolis next season, he'll be suspended for the opener as well.
Richardson finished the 2014 season with only 519 yards and three touchdowns.
