The crazy part is Jones vs Stipe was booked way before before Aspinall even won the interim belt. Aspinall was a relative nobody when Jones destroyed Gane and called out Stipe the same night.
Dana and the UFC made it clear they weren't going to scrap Jones vs Stipe just because they handed out an interim due to injury. Yet the fans were in some kind of silly uproar once the Aspinall hype train got going. Jones never cared for Aspinall and he wasn't even relevant until Jones was recovering from a serious injury.
The risk reward just makes no sense for Jones, he destroyed the #1 HW contender in sheer minutes and all the fraudulent fans could say was "GANE SUCKS" or "GANE WASN'T READY", despite the fact Jones was coming off a historic 3-year layoff to fight a #1 contender, not even Dominick Cruz was out that long when he came back to defeat TJ. Jones does historic never before seen feats but the haters just never stop.
Now the truth has been laid bare, that Aspinall isn't nearly as good as people believe. He is worse or on par with Gane, and that's okay. But Jones would rather fight closer to his optimal fighting weight with a real champion. Aspinall has no defenses, never won a real title, like the whole thing is really good marketing.
