His style required him to be in extreme physical shape. You could see signs of him losing focus way before his current losing streak, going back to the Karmazin fight. I'd love to see him come back, but it seems very unlikely at this point. It's a damn shame if his demons really end up getting the better of him.
I know Kassim personaly from training here in south florida. Kassim just isnt hungry anymore. I usually catch him at Duffy's when theres a PPV fight on ( like when he was getting bent a week before that K9 fight ). He isnt the same from when we where training a couple of years ago. That hunger has died out but can you blame him ..... from what he came from to having some money.
