Terence Crawford has already stamped his ticket to the International Boxing Hall of Fame with his campaign through four weight classes – but another Canastota inductee believes that Crawford’s plans to jump up two more divisions to face super middleweight champion Saul “Canelo” Alvarez is too much.

“I don’t like the fight,” Juan Manuel Marquez said in an interview with Fight Hub TV. “Terence Crawford is a good fighter, but in the sport of boxing we have weight classes. Terence Crawford is a good fighter in super lightweight, welterweight and super welterweight. I remember when Terence Crawford fought with [then-154lb titleholder Israil] Madrimov.”

Crawford defeated Madrimov in August to capture the WBA junior middleweight title, nabbing a belt in a fourth weight class after being the Ring champion and WBO titleholder at 135, undisputed at 140 and undisputed at 147. However, the unanimous decision over Madrimov was relatively close: 115-113 (twice) and 116-112.

“He looked slow. He looked with no power. And two more divisions is, I think, it’s a tough fight for Terence Crawford,” Marquez said. “But Terence Crawford is a great fighter. He has great defense. He has good combination punches. But I think the weight class is no good for him.”

Crawford hasn’t fought since the Madrimov bout and isn’t expected to return until he steps in the ring with Canelo, likely in September, which allows him more time to add pounds to his frame and test his performance in the gym. Canelo, meanwhile, first will take on William Scull on May 3 in Riyadh, Saudi Arabia.

Marquez himself tried to go up two weight classes, and against one of the best boxers ever, at that. After campaigning primarily at featherweight, Marquez had a brief stint at junior lightweight and then arrived at lightweight in 2008. He went from his come-from-behind TKO over Juan Diaz in their Fight of the Year winner in February 2009 to moving up to challenge Floyd Mayweather Jnr at welterweight that September. Marquez weighed in at 142 pounds while Mayweather, who won a wide decision, was 146lbs.

Marquez then returned to lightweight for two more bouts before moving up to junior welterweight in July 2011. Four months later, Marquez came in at 142lbs for his third fight with Manny Pacquiao; that bout had a contractual weight limit of 144lbs. In their fourth match, which Marquez won with a spectacular one-punch knockout, he stepped on the scales at 143lbs while Pacquiao was 147lbs. And for Marquez’s split decision loss to Timothy Bradley in October 2013, Marquez weighed in at 144.5lbs; Bradley was 146.
