I'm back, ladies and gentlemen, after being banned for the weekend for some unknown reason. Anyway, Dawson should stay right where he is at. If he is going to move up, which he isn't, it would be to CW. Dawson doesn't have the frame to be a HW.
Chad should continue taking care of business at 175. He only needs a couple of good fights to keep people satisfied until the Super 6 fighters are free to move up and face him, so there should be enough good fights to keep him occupied for the foreseeable future.
