Jenkis detriment was his bad attitude. Only the bad sticks out in his career with the Cowboys. He got lit up in the GB game and didn't seem to care. He wuss-ed out and just let Jacobs waltz in for a TD. He didn't rehab at Valley Ranch. He pouted when he didn't get the contract he hoped for. I think Jenkins thought he was better than he actually was and didn't work as hard as he should have. He is a player teams need to keep on a short leash, no long term contract for him.
