It's not bollox. You've never put on a glove in your life, never mind in the heavy division, have zero actual knowledge. You're an armchair pundit who's knowledge of pugilism is restricted to getting bitch slapped for your lunch money at school. There's a notable absence of boxers queuing at your door for technical, sporting or business advice.
Few men alive could do that to de Mori. Perhaps you'd like to list the fighters currently competing and in match form who would qualify to step on the ring with de Mori? You'd fit them in the same room with little difficulty. He'd take your head off your neck in three seconds so you've neither the technical expertise or moral high ground when it comes to criticising a pro boxers performance. Compared to Haye, on that day at that time he was outclassed and that's about the only thing you can realistically say. On his worst day, hungover with the sheets and the flu he'd still put you on the canvas in seconds.
I bet you're the sort who'd criticise F1 drivers, while conveniently ignoring that even the slowest are leagues better agreement than you. Discuss, observe, comment by all means, but you're in no position whatsoever to actually judge. You criticise it for being unsporting, while yourself not even being enough of a sportsman to acknowledge that even the worst of them are martial athletes of a calibre you never will be. Your lack of humility is astonishing considering your ignorance and lack of experience of the sport.
