Francis gets beat by Jones. Jones is too smart to get sucked into a brawl and Nagannou would gas
Francis has a shit gas tank. Jones finishes him in the 3rd.
If Jones spent a year bulking up he would own the HW division. He is too smart of a fighter to lets anyone get ahead of him. Sure a clean punch from any HW can knock anyone out but Jones has shown to be smarter than everyone else in the Cage.
Francis is getting so overrated. The guy lost to fucking Lewis a few fights ago
Jones would lose against both Stipe and Ngannou in my opinion.
Listen, Jon is a smart fighter, but honestly, the thing that made Jon Jones so dominant in nearly all of his fights so far is the fact that he's got a ridiculous reach (215cm/84") so he's able to pick most fighters apart rather "easy" from the outside - if those fighters do enter the range where they'd be able to hit Jon though, Jon either uses his wrestling, or he clinches with them, where he again uses his height along with his wide reach to dominate.
Stipe Miocic has got the same reach (203cm/80") as OSP and Bonnar , who're the rangiest fighters Jon has faced, even surpassing Gus, and Ngannou even has a reach of 211cm/83" so Jon's reach advantage would be diminished against Stipe and would be almost non-existent against Ngannou.
So it won't be as easy to stay on the outside for Jones with Stipe, and nearly impossible with Ngannou, who's very explosive and rather fast.
With his power not even being really good for a LHW, Stipe and Ngannou will be way less impressed by Jon's power and won't back up nearly as easy as Jon's past opponents.
If they do get close to Jones, Jones clinching-game won't be as effective as against the LHW's as well, since Stipe and Ngannou are as tall/taller than Jones, and way stronger, especially Ngannou.
If Jon decides to wrestle with both, he - despite being a great MMA-wrestler - will have a lot of trouble, since Ngannou's tdd is 1) not as bad as some people make it out to be, and 2) most likely has improved, and even if his technique ain't perfect, being strong as hell definitely helps defending takedowns and it's the most obvious thing that Ngannou is way stronger than Jones (even if Jones bulks up). Stipe on the other hand, might not be as strong as Ngannou, but is still a natural HW, so he'll most likely have a strength-advantage as well against Jon, and his tdd + defensive wrestling is actually really good.
If Jones (for whatever reason) would try to box with either Stipe or Ngannou, he'd get starched in the blink of an eye, since Jones is not a good boxer and has questionable boxing-defense/head-movement.
Now for those saying that Jon would be stronger at HW than he is at LHW - well, yea, if he adds muscle to his frame, he certainly will gain strength - however he's going to gas out a lot faster if he's trying to get strength-wise on par with Stipe, let alone Francis. If he's going all-chubby, his cardio will most likely be (pretty much) as good as at LHW, but the strength-disadvantage would be bigger.
This pretty much sums up, why there are weight-classes; you might get swole and get as strong as the guys a weightclass above, but then you'll almost certainly lack cardio, where if you're going to just gain some fat, you're at a strength-disadvantage.
If either Stipe or Ngannou pressure Jones just a bit, they'll eventually get close to him and i'm very confident that this would be a nightmare for Jones, because having a good chin goes out of the window if Stipe Miocic or the worldbreaker Ngannou hit him.
To beat them, Jones would need to be at his very best and fight the perfect fight, giving them nearly zero opportunity to land anything or get close to him.
..and i'd like to add another thing: if one-legged Thiago Santos low-kicks made Jon limp out of the arena of their fight, what do you think is a single low-kick from Ngannou gonna do? (At Ngannou's gym they're saying that his low-kicks are freakin' devastating, so i'm not making things up - just to be clear.)
