For me this fight is way more interesting than main event, as these two are potential next heavyweight champions. With Jiri and Pereira it looks like it is already clear who is going to win. UFC decided to throw Jiri, a guy who returns from injury and havent fought for more than a year, into a monster with concrete fists. Imho Pereira gonna land his left hook and finish everything in first or second round. But in a fight between Pavlovich and Aspinal, its power against tactics. That is really interesting to watch. As I have never seen Pavlovich defending against bjj.
