I got Fiziev as he has more tools in striking than Justin Gaethje, has good enough wrestling defense and has improved cardio as seen in his match vs Dos Anjos. But I don't think Fiziev will pulverize Gaethje. It's going to be a good fight with Fiziev edging it out.
One thing with Gaethje tho is the shots he's taken throughout the years could be accumulated and is ready for a KO.
As for Usman, he'll improve his chances of winning and make his current line look like value if he goes out there and have a wrestling heavy game plan. IMHO. I think he will... He just wants his belt back.
Justin Gaethje's wrestling is over hyped in my opinion. He has never shown that he wants to wrestle I cannot remember a time where he tried to take down his opponent. Instead he likes to have a stand up heavy game plan and likes to knock people out. He could have easily won some of his losses if he knew how to wrestle I know he has a long history at high school level and I think he was a state champion but he has not shown that in the UFC and I think he will try his same game plan of standing and trying to knock out Rafael.
