no... he's still in nappy time!! what's next?? :huh get KTFO over and over again... like Roy Jones Jr. :yep :deal
He can have 10 new trainers and it won't make a difference. It will be the same old routine of him fighting carefully selected opponents that can't punch, continue to deceive his gullible fanbase and cash out against someone that will inevitably catch him cold. Fact is, Khan was getting stunned, dropped and hurt at 135. Hell even at 147, where he apparently was at the "right weight", he was getting stunned by single shots from Collazo who in his prime was a gatekeeper at best and isn't a power puncher. He's most likely doing what he did before. Move down, take some easy fights and cash out against Brook. I won't be surprised if Khan dominates Brook just as long as he can perform fine without this KO totally affecting his confidence.
Change trainers, fight 2-3 feather-fisted journeymen, fight a decent fighter - get KOed Rinse and repeat.
