He already has, he's been coming across as nastier and nastier in the build ups to his last few fights, and the pathetic running against Postol sealed the deal.
Mate! This is by far the worst main room of ANY boxing forum on the net to "learn" from. What most know on here about boxing you could write on the back of a stamp! 99.9% of the users on here are the same ones you'll see on boxing pages on Facebook and they're throwing up gang signs, look like basement dwelling neck-beards or have Tony Montana covers as their FB page. And then they will be throwing Mayweather's statistics out there or backing EVERY black fighter to the hilt. Bufoons, essentially. Guys like yourself, IB, Burt Bienstock are rare finds on boxing forums nowadays.
