More like that would be a POS move by him, that's like Khabib calling out Tony ffs lol, or Khamzat fighting Diaz or Yanez fighting Edgar but these 3 are honorable to not fight guys who are over their prime but Jon is a POS Scumbag.
Edit: Also, we will respect Jon if he beats Sergei, beat Sergei then and we will stop discrediting Jon, but I don't discredit that he is the GOAT and the No. 1 MMA fighter in history tho, cause as of rn, no HW or LHW will beat Jon, but we like to think that Sergei has the highest chance, he's the No. 1 contender, on a long streak, a complete HW that's in his prime and ready and hungry to fight and drink from HW's blood, also Alistair is a weird fighter, he either be on someone's highlight or be on a fighter's highlight, also you why you think Jon wouldn't be respected? but if we're gonna talk about something else, Jon is a POS but Alistair is a real one, both are blacks but at least Alistair is a real one.
