Usyk is seriously talented and a fantastic fighter, but Loma's talent and ability is supernatural. Like you say, it's almost like he knows exactly what his opponent is going to do before they do and he's so quick to react. You don't win all those amateur fights and lose just one whilst competing at the level he did unless you're a freakish talent.
I imagine his speed and agility would have Wach tripping on his own feet. If he can avoid Fury's headlocks and elbows :think which I think he can that would be interesting. A meeting between him and Parker will probably eventually determine who sits atop the Iron Throne.
He'd just have to be ultra careful not to get clipped by someone who had a significant size/weight advantage over him who can really bang. He would run rings around a lot of HWs though, IMO. I've only seen a couple of Parker's fight so far but I really like the look of him. Seems like a really cool guy as well.
