I don't think I'd go do far as to use the word 'disgust', but I think he looks foolish trying to look like a tough guy and celebrating every small accomplishment he makes. It shows a lack of awareness and maturity to me. He's a third string guy, not the man. Know your role, shut your mouth, and do your job. Focus on getting better and doing the things you need to do to play more and eventually be the man.
Seattle wanted him to do that and to eventually be Lynch's replacement. And because he failed, they're paying Beast Mode big money to stick around, signing Fred Jackson, and holding onto undrafted free agents. Hopefully, being traded away for table scraps and replaced by a guy off the street serves as a wake up call that he's not as good as he seems to think he is and if he doesn't work harder and get better, he might end up as nothing more than unfulfilled potential.
