Given the Bears continuing narrative of "soft tissue" injury I'm having a hard time giving Gordon the benefit of the doubt. As you said, it's "I've lost the desire to play football", if that's the case, then horsefeathers retire.
Bears don't gain anything by cutting him otherwise, he'd be an x-Bear, he probably already is an effective x-Bear. Poles deserves a lot of horsefeathers, he's horsefeathered up way too much, I'll give him a pass on Gordon. Don't think it's possible to glean he's a once I get paid I'm checking out dude or dud on draft day.
