Where do you separate "falling apart when getting hit" and "rocked from a shot and fighting worse from it" though? Nobody can withstand being rocked. That's different from falling apart when getting hit. If a guy is getting clipped when he comes in, I expect him to change gears and reassess, especially after getting hit with a good shot like a big elbow.
Brock = falling apart when getting hit.
You also mentioned MJ as a testament to that, even though MJ was clearly just pressuring him properly and outclassing him on the feet. Sometimes people fight better opponents. Tyron Woodley isn't hesitant and doesn't fall apart on the feet, Rory just picked him apart and jammed him up, similar to MJ and EB.
I just think you rewrite how things happened to fit whatever narrative you're pushing. He got sloppy on the ground? The sub happened in like 2 seconds and the d'arce is TF's signature move. Again, what's the difference between being sloppy and just outclassed in a split second maneuver? Chael didn't get sloppy against Maia, he was simply outclassed.
That **** was locked in ASAP by a guy known for his brabo. He's obviously trained to hit that off a quick scramble a LOT.
