In a strange way, even Michael Bisping’s official retirement on Monday came against a certain lay of odds. After he lost to Kelvin Gastelum in Shanghai — in what will go down as the most ill advised idea of his 39-fight career — he was still angling for one last fight in England, where it all began for him back in 2004. Given what a pugnacious, confrontational, and ultimately stubborn bastard he can be when it comes to fighting, it was hard to argue with him. Arguing is the one wheelhouse Bisping’s most comfortable in.
