Izzy is actually a humble guy. People really put him on the same level as Jon Jones, Conor, Mike Perry etc. just cos he said/did some corny things, or tried to market his fights. I s2g if Izzy did half the things Darren TIll has done you wouldn't hear the end of it.
Anyway, I don't actually hate anyone enough to "wish" to see them be humbled. However, part of me wants to see how Khabib's cult fanbase would react to see him take a loss at 170. Nobody is unbeatable, and saying you're P4P #1 & your fans calling you the GOAT, but refusing to move up leaves a bad impression.
