Aspinall needs as much cage time as he can get before Jones, so the more fights he has the better.
Jones doesn't loose to the Sergei's and Gane's of the MMA world, he is too smart and well rounded to let that happen.
Even old mileage Stipe has enough in him to defeat Gane, I feel the experience and skill of his standup is better then the fresher bouncier Gane and lets not forget that any decent wrestler that commits will be able to exploit Gane's game in that area.
I did not mention Aspinall fighting Jon, but yeah Aspinall needs more experience by keep fighting more and more.
Yes, I kinda agree that even a current Stipe would be a tough fight for Gane, but I think Gane would still get his hands raised due to being him still in his prime physically, has a fantastic striking and Vicious KO Power, would do everything it takes to win as he doesn't wanna take another embarrassing loss to a fighter from an older generation.
And for Stipe, I don't think Stipe would be feeling motivated to fight again unless if it's for the title, but if the motivation thing is fr like we've seen from Jon winning against Gane due to feeling motivated, then I kinda wouldn't mind seeing Stipe vs Jon (I'm saying if it is fr, if the motivation thing is a real thing), but Idk about Stipe beating Jon as Stipe probably not in his prime physically, but a prime Stipe would've been a trouble for Jon.
Edit: also no, I disagree, Pavlovich is a HW that's in his prime, reason why Jon beat Gane is no one knew what type of fighter Jon would be at HW, no one was ready for him, he would've done that to any HW, not necessarily Gane, and also at the same time, Gane was still green, he doesn't good wrestling or good grappling enough to match up with a wrestler of the same caliber like Jon, but now Jon wants to pick a fight with Stipe who's 41 years old, Jon gets motivated when he be fighting Legends and channels his anxiety to excitement, but when he fought guys that aren't on the same skillwise like the legends he fought in his first title defenses like Reyes, Santos, he started declining a bit and feeling less motivated, so if Pav would fight Jon, Jon would feel less motivated, Jon needs fear to feel motivated, and Pav is the fighter that Jon would look at him and wouldn't feel intimated, and for that, Pav would be the HW that can figure out Jon and put him away, even see this video, he tells about the difference when Jon fought Shogun, Rampage...etc, and when he fought Santos or Reyes.
