Charlo should theoretically be his mando, and I really doubt Callum will ever make 160, as It's already a miracle how he makes 168. So Charlo by a mile.
Smith. He's not just a threat, he wins this fight 10/10 times. If groves can't live with Smith, then what is Canelo going to do? Canelo is like 3/4 of the size of Groves. Smith will put Canelo to the canvas within 6 rounds. On the other hand, Charlo gets murdered by Canelo. Charlo is an inactive hypejob bum. He's fought nobody and he's somehow being hyped up as the new king of the division. It's nonsense. Canelo, GGG, Andrade, BJS, Jacobs...they all DESTROY Charlo.
