You don't think playing through his shoulder last year demonstrated heart?
The guy's a bit of an odd duck, and it seemed from the outset that the team just wanted to work him through his rookie deal and be done, but I've never understood why. In a league where good cover guys are so hard to find, you'd think he'd have been welcomed with an extension, but it just wasn't in the cards for some reason.
Now, I understand why another team doesn't want to sign him to a long-term deal given his shoulder. But the guy sure got a bum rap in that deal (not that it was Dallas' fault, it was just the breaks). All-in-all, I think he handled what had to be enormous disappointment with a fair amount of class. He rehabbed on his own, as was his right, stayed away from some voluntary offseason stuff, and then came back in for mandatory work and--to my knowledge--never said 'boo' about the organization or the team once he got to work after getting demoted to a backup CB heading into his contract year.
That said, it'll be interesting to hear what he has to say about Dallas now that we're in the rearview mirror.
