If you follow the technical merits how the sport should be, then no.
But taking out Volk and Max back to back by KO is insane. That is basically the hardest 2 fights in a row of any division recently. Also not only has Volk fought for the LW title 2x right before, but Max was a ranked LW who KO'd the #3 in Gaethje, who is probably the guy who gets the title shot if Topuria doesn't.
UFC opened the floodgates long ago with Conor getting a titleshot at LW after Aldo. We've seen so many guy get title shots off a loss or 1-1 in their last 2 over fighters who actually deserve it and are 6+ wins and no losses. Also you have to be sort of pedantic to say beating Max at LW is different than FW because of the 10lb difference.
From Islam's perspective the only true LW he's managed to defend against is Dustin who was KO'd 2 fights before and was getting beat until he came around to finish BSD. Well also last minute #10 Moicano as well. If you think about it Islam hasn't beat anyone good at all that wasn't a former FW. If you ignore last minute matchups like Moicano, Green, Hooker, then everyone ranked was a former FW since Arman the first match. Since 2019, only Drew Dober has been the only guy who had a full training camp and never made FW before that Islam has beat.
