Canelo got wobbled down at welter. He doesn't have a true iron chin. The problem is landing clean on him, it's what a lot of fighters mention. Let's put it in perspective. Can anyone see Froch getting wobbled by Cotto's brother? And can Canelo, who was hurt by Golovkin RH's a couple of times, take flush RH's from Groves for all those rounds (a RH considered bigger than Golovkin's according to Murray)? Froch is naturally bigger, just not a huge cutter, but Canelo is at 168 now so we're talking about what he can take at that weight class. He absolutely can get KO'd, it's just landing the shots is hard on him.
Yeah, that guy. 24 wins out of 28 by KO. But we'll never find out because Canelo is closing out his career with cherry picked fights against an assortment of garden gnomes and circus midgets. He's too scared to fight a guy with power and size.
You know you can stop someone without them ever hitting the canvas? Thats how Benavidez will stop him. Just batter him on the ropes and the ref stops it, or towel goes in. Thats how he usually stops opponents anyway so Canelo's chin won't be the issue.
Beterbiev, Benadivez, and quite possibly Bivol if he rematched him (although it would not be a KTFO, more by accumulation)
