Ra's thread reminded me of this fight. Sharmba got off to a good start, winning rounds and dazzling Kostya with some very impressive footwork and lateral movement until Tszyu wore him down with his roughhouse/borderline dirty tactics. https://streamable.com/trkf
It's too bad the whole thing didn't play out, but I remember thinking Tszyu was catching up to him as Mitchell was slowing down.
Mitchell was throwing his body into KT as I recall and got spun roughly off accordingly. Good tactic to use against a rushing fighter in a very entertaining fight - must watch again.
Mitchell was very slick, but lacked durability against strong, powerful guys This was first exposed against Lavander Johnson in 1994. He didn't have the strength to beat a guy like Kostya.
