Mickey Gall is well respected considering his trash record (young enough so not really his fault), I would say George Sullivan was past it but I am not even sure he ever had it, his UFC record was never great. Sage is his best win by far and had a few decent wins since then, is an okay fight BUT not the smartest for Gall. A win does little for him and a loss would be tragic at this stage, his first win would be put down to fighting an inexperienced younger Sage.
I would have liked to see him call out someone like Jake Matthews.
