Yazdani is the most physically imposing wrestler at the weight. If Brooks couldn't handle this guy's physicality, he wasn't going to handle Yazdani's.Styles make matchups. Yaz goes with a ton of forward pressure and underhooks. As Brooks has shown against Hidlay, that doesn't work very well against him. Now, I am not saying Hidlay is near Yaz's level, but, conversely, the Bulgarian's style confounded Brooks and put him into very uncomfortable territory with physicality I don't think Brooks may have ever experienced.
Yaz is so good that he may very well have been Brooks, but I think Yaz would have had to weather a late storm, much like how he had lost to DT in the past. Yaz's style just isn't conducive to winning late and I am not sure he could push Brooks around the mat early, like he pretty much does to everyone else...
Brooks beat Hidlay because he's a much better wrestler, not because of Hidlay's style. Yazdani beat Hidlay way worse than Brooks beat Hidlay.
