Ennis, who once chased a fight with Crawford at 147lbs, believes Canelo's size and strength will be too much for 'Bud' to handle. He told Fight Hub TV:
"I think you gotta lean more towards Canelo, because like I said before he been putting big guys out and down. And Canelo not even really a 68 pounder, he probably really should be at 60 maybe and he been hurting these guys."
Canelo has been a dominant force at 168lbs since 2018. He's racked up wins against Callum Smith, Billy Joe Saunders, and Caleb Plant on his way to becoming the undisputed champion. The Mexican star has even found success at light-heavyweight, knocking out Sergey Kovalev in 2019.
Crawford, on the other hand, is making a big jump in weight. He's moving up from welterweight (147lbs) to super-middleweight (168lbs) without any fights at middleweight in between. His only experience above welterweight was one fight at super-welterweight last year.
Ennis points out that Canelo has hurt opponents who weigh close to 200 pounds on fight night. He thinks this power advantage could be a problem for Crawford.
The former champ also suggests that Crawford should've taken a warm-up fight at 160lbs before challenging for the undisputed super-middleweight world championship. This lack of experience at higher weights might work against Crawford, according to Ennis.
Both Canelo and Crawford are considered pound-for-pound stars, but their paths to this fight have been very different. Canelo has fought as high as light-heavyweight, while Crawford has spent most of his career at lower weights.
