Lewis knows a thing or two about boxing. He won Olympic gold, then turned pro in 1989. He went 25 fights without a loss to start his career. Lewis held the WBC Heavyweight World Title and avenged both of his career losses. In 1999, he became the undisputed champion. He retired in 2003 after beating Vitali Klitschko.
Now, Lewis watches boxing from the sidelines. He's impressed with what he sees in Crawford. The undefeated fighter has won world titles in four weight classes. He switches stances, making him tricky to figure out. Many think he's the best pound-for-pound boxer right now.
Crawford's achievements speak for themselves. He's been undisputed champ twice - once at welterweight and once at junior welterweight. Recently, he moved up to 154 pounds and won the WBA World Title from Israil Madrimov.
In a chat with Fight Hub TV, Lewis couldn't help but gush about Crawford's skills:
"Let me tell you about Terence Crawford, that man is Kung Fu. You know, when you watch a martial arts movie, you know, you think of him, he's just full with his style, great with his style. He's got power, he's got poise, he's got speed, he's got movement, he's got the full package and no wonder he's undisputed, double undisputed that's quite remarkable."
Crawford's next move might be his biggest yet. He wants to fight Saul 'Canelo' Alvarez. For Crawford, it's the only fight that really matters now. Lewis thinks if Crawford wins that one, "we've got to bow to Crawford."
But there's a catch. If Canelo says no, Crawford might hang up his gloves for good. Right now, Canelo's taking it easy. He says he'll look at offers when he's not got a fight lined up.
Crawford just moved up to 154 pounds and grabbed the WBA World Title. He's setting himself up for the big one. Whether it happens or not, Crawford's already made his mark on boxing history.
