That's according to his manager Alex Davis:

"Well, I'm not sure exactly what the problem or problems were. I tryed [sic] hard to avoid, but Dana wasn't listening. It unfortunate, but Todd's an asset and he will keep fighting. He's a young kid that gets a lot attention."

SI.com's Josh Gross passes along the quote from Davis about the apparent difficulty in dealing with the talented but ornery Duffee, who set the division ablaze with his record-setting knockout over Tim Hague, only to go belly up after a KO loss to Mike Russow just a couple of months later. Any chance he shows up in Strikeforce? And what kind of impact can he make if he does?
