Sure Collazo might not be a world level operator, but he has faced opponent better than Kell. Khan has fought: Judah, Peterson, Garcia, Barrera, Kotelnik, Malinaggi & Maidana. He was cheated against Peterson. I do agree that Khan says some pretty stupid things, but you gotta admire his heart, i mean he keeps getting knocked down and keep coming back up, unlike the clown like: Dirrell. His fights are entertaining, but people basically labels him as a bum. Collazo is dangerous, because he got one punch explosive ko power. I remember people saying that Khan was scared of Maidana and faced him and beat him fair & square. Khan's weakness is his chin and yet he keep on fighting boxers with real power. I think he deserves more respect, even though he says some ******ed stuff now and then :deal
