Thing is Mc, Lewis fought many genuine world class heavyweight opponents and beat them all. He was an active boxer and didn't duck anybody. Fury's only credible opponent was Wilder and like Usyk, is more a cruiserweight than a heavyweight. Imo, Wilder filled a gap because there wasn't a genuine world,class heavyweight at that time.
Whatever Fury achieves in his career, it will always be because his height and weight advantage. Not because he is a world class boxer. It's always like matching a 14 year old undeveloped kid with an adult. It's never a fair contest.
