I'm not sure where the bum talks come from. He just gave Khan hell all while suffering from a gigantic stylistic disadvantage.
Good fighter, made the right call by brining in John David Jackson. However when Khan are talking about he wants the Mayweather fight, you gotta look exceptional against Algieri, and even though Khan won fair & square it was defiantly not convincing. His defense is still pretty bad and his greatest asset: Speed looks like it were a bit on the downside. Thurman would slaughter him within 3 rounds.
