I watched it, and loved it!
The ref told them to fight, refs talk to ringside judges all fight long, it just happened at the exact moment of a KO. There is no rule in boxing that says you have to touch gloves or hug or kiss if your opponent comes in for one... you go out there and tag 'em and knock 'em the fuck out and that's what Floyd did! I give him all the credit in the world. They touched gloves, Floyd measured him up and dropped him. Fuck the haters!
