Looking at OP's list, damn MW is such a wasteland now.
I know Till doesn't really deserve it, but I'd give him the next title shot, simply because him and Izzy could deliver on some promotional gold before Till getting whooped.
Oddly enough, Usman at MW, Wonderboy at MW, and dare I say Uriah Hall, would be good match ups to put against Izzy. Izzy vs Hall would be super interesting since they both have similar striking backgrounds. Cannonier could beat Izzy too. Izzy gets hit more than the UFC shill machine would have us believe, and Cannonier's got that power.
