Dober, like Jourdain, is a guy who is typically getting outgrappled by the people he fights. Not the other way around. Also like Jourdain he went in there with the intention of striking and then got busted up and bloodied at which he decided to implement his wrestling. Drew is a big, physical guy who wrestled in high school but he's a fairly mediocre grappler. He's got a 17% takedown accuracy across an extensive UFC career.
I won't deny that momentum is on Silva's side and is a big factor into my picking Silva in the first place. But Bryce really hasn't been known as a particularly chinny guy until lately. It seems like a... revisionist narrative just because one of the hardest punchers the division has ever seen connected perfectly on him with an overhand and slept him. He had never been KO'd prior. The only other man who was able to drop him prior was Topuria, i.e. a guy renowned for his power, hand speed, and extremely dangerous boxing combinations -- the same guy who cracked the most legendary chin in the history of the sport.
I mean is it possible that Mitchell's chin is cracked and that the punishment from Topuria and Emmett changed him? Sure, absolutely. I don't deny that for a second. We see that all the time. Furthermore, I don't even think it's necessary for that to have been the case. Silva is clearly "built different" when it comes to explosiveness and timing so I think he has 100% the ability to put Bryce down in any case considering others have (and I'm picking him to do so)... it's just that I don't necessarily agree with the idea that Bryce is chinny simply because it doesn't really account for the context of who he's getting hit by and under what circumstances lol.
I don't even like the dude at all, I'm just a stickler for these things. It's like when people say that Curtis Blaydes has a glass chin because they look at his Wikipedia profile and see that all of his losses are by KO/TKO, but don't bother to look into it beyond that.
