Anthony Joshua, like most of us, was stunned when Terence Crawford dropped the news.

The former three-division undisputed champion and five-division belt holder recently announced that he was hanging up the gloves.

Although he’s 38, Crawford looked like a man who wasn’t close to being done in his convincing victory over Canelo Alvarez to become an undisputed super middleweight champion on September 13. However, Crawford (42-0, 31 KOs) evidently has had enough.

Joshua wholeheartedly respects Crawford's decision but doesn't believe the future first ballot Hall of Famer should walk away just yet.

The former two-time heavyweight champ spoke to Rick Reeno on the "Mr. Verzace Podcast" before his fight with Jake Paul on Friday.

“I feel like Terence Crawford has got so, so much more to give,” Joshua said. “But it’s not just physical, it’s what’s going on in his mind. He’s been in the game for a long time, so maybe he’s like, forget it, I’m done mentally, even though physically he’s good.”

While he accomplished more than most, Crawford still had plenty of options. For starters, Alvarez announced a desire to run things back in the second half of next year. And Jaron Ennis and Vergil Ortiz head a long list of notable potential foes who have repeatedly called him out.

Nevertheless, Crawford’s pugilistic cup is full as he now awaits that eventual call from the Hall. If he doesn’t get the itch to return, Joshua (28-4, 25 KOs) will be somewhat disappointed. With that said, he understands that Crawford has given his life to the sport and has earned the right to go out on his own terms.

“I would love to see him continue fighting,” Joshua said. “I think he’s got a lot left, but we have to live and let others live by their own rules.”
