I don't see Colby fighting again at 170 unless it's big name fights. I could see him fighting someone like Dustin if he decides to move up, but I can't see Colby fighting Wonderboy, Shavkat, or even Belal. Maybe I could see him moving division, but even that's a tough sell. I don't see him having much success against a guy like Islam, and Colby isn't a big welterweight, so middleweight seems absurd.
