The Bears used their first round draft pick on him. He was like the 4th overall pick in the 2005 NFL draft. Then Benson had contract issues and blew off training and missed all of the summer training. He then had issues with the Bears coaching/management. He was in contention with Bears head coach Love Smith, and in my opinion he diminished the [successful] career of running back Thomas Jones who was playing great for Chicago. Then, to top things off, Benson went and fortified his criminal record before the Bears decided to kick his ass off the team for being an idiot.

There are two sides to EVERY story, and the other side is that the Bears management is awful. The Bear's management is just as responsible as Benson is....and I doubt I'll ever be able to forgive the Bear's GM either.
