On ability, Ricky Burns, I always liked Ricky and never heard a bad word about him, I always thought he was a solid fighter but I didn't think he'd beat Katsidis, Martinez and a couple of others. Burns became a two weight world champion and I was very happy to be proved wrong. On personality, Khan, I remember supporting Khan when he was 17 years old at the Olympics, he seemed a humble and bright young man but as soon as the medal went around his neck he turned into a completely arrogant and delusional a**hole.
You're just proving my point. Your unwilling to accept reality. Stiverne was ranked in top 5 by Ring, one of the few hw's to beat another ring top 10 fighter (did it twice), and was beaten by Wilder who also beat a guy who arguably beat another top 10 hw in Glaskov. Still undefeated with 33 kos in 34 fights. In the modern hw division, you don't get much more definitive proof of being in the top 5 than that. Regardless of whether you agree with the specific example, the point of the thread is to admit you decided you were wrong about a fighter. Shows a degree of mental strength your showing you lack.
Sounds like you may change your mind too late, after the facts have long since passed you by. (Almost) Everyone loses eventually. Can you name any fighter you were wrong on? Back when he was getting hyped 3 years ago or so, I bought into the horrible chin arguments, and the talk that Audley Harrison knocked him down and had his way with him in sparring. I considered Wilder a sub top 30 hw. While this era of infrequent top contender v top contender bouts make conclusions of a fighters place more difficult, its hard to make a rational argument Wilder isn't top 5, basically impossible that he's not top 10. I was wrong about him in my original judgment. I'm sure you've been similarly wrong about plenty of fighters too, just unable to acknowledge it.
