I'm really not sure what to make of it, not sure I want to see Stipe against Jones either.
The only fighter in UFC roster that can ask for a title fight after year of inactivity is Conor McGregor. Jon Jones is not the same star as Conor. Jon Jones might want what ever he want, but I think he should test his strength first against other opponent. That would be more profitable for UFC. If they throw him on Ngannou, and I think Ngannou would win, will people be interested in Jones then? Let him first try to win top heavyweight.
Remember when Adesanya tried fighting agains Jan Błachowicz ? How small he looked, and how easily Jan threw him to the ground. Wiki say that Jones Jones weight is 93kg, Ngannou 113kg. How much could Jones gain? 10kg? There is still 10kg difference. Ngannou would run over him without even noticing.
No no, that's really not the correct information here. What wiki is saying is that he's fighting weight is 93kg. That's because his division is LightHeavyweight and the limit there is 93kg, so that's the number wiki says is his fighting weight. It's still on that number because he actually hasn't fought in another weight class (since fighting in LHW) and therefore there is no record of any other weight. Now, keep in mind that fighters in all weight classes, for the most part, cut weight to get down to the limit of the category. LHW is no exception, Alex Gustafsson said he personally get's 'fat'' in between fights, and we have reports of fighters like Tibou, Till, MacGregor, Khabib Nurmagomedov, and so on, that started camps as high as 20 to 25 kg above the limit of their weight class and then cut down to the required weight.
So let's put Jones at a conservative 105kg walking weight when he is fighting at LHW (although I think it's more). That's all before he started putting on mass for fighting at HW, and that's quite different than just the walking wait, he is actually training and adequately addressing his nutrition to accommodate those gains.
Now let's look at the other side, Ngannou. His fight with Gane was recorded at 116kg. Heavyweights usually do not ballon much after weigh-ins because there would be no advantage in that as opposed to some lighter classes, and they are already way below the 120kg limit that the class has. Miočić for example had a walking weight of 109kg.
So with all of that in mind, the actual bout would not be so much different than for instance Miočić and Ngannou had, 5kg here or there, but that's mostly it, and at that weight class, that's more than tolerable of the lower weight fighter.
