One could definitely add Krylov to the list, but Rakic, Reyes and Walker just were the ones on top of my mind and i haven't seen anything of Krylov so far (literally speaking) but looking at his record, it makes me skeptical that he's been submitted 5 times already. To be fair though, he's had 31 pro fights at 27 years of age, so there's still a lot of room for improvement!
With Walker it really is kinda difficult to evaluate him as of now, since - like you've said - we've only seen him for an extremely short period of time in the UFC, but i think it's really not far fetched to acknowledge that he's got serious talent and the physical tools to be a force to be reckoned with at LHW.
Regarding Volkan - Latifi + Volkan - Reyes i agree; i also think that Volkan - Reyes was closer than people give Reyes credit for and it should also be noted, that Volkan is still only 29 years old as well and a difficult matchup for anybody who's not that good of an offensive wrestler.
..and yeah, Rakic definitely looks very promising imo.
Well, it's true that we've never seen anybody testing Walkers wrestling/takedown-defense in the UFC so i think he's definitely in for a good test against Anderson. But even if Corey Anderson beats him with his wrestling, i don't think that Johnny Walker would be much less of a prospect then. I mean: it's better to be dominated by a wrestler, than it is to get lit up by a striker on the feet (most of the times) and with his young age, Walker still as a lot of time to improve.
Reyes really is the least spectacular of the three, but having said that, his rather conventional approach to striking shouldn't fool people into thinking that he's an average striker; i think technically he might be one of the best if not the best in the division - that is not to accuse you of underestimating Reyes though, just stating my opinion towards him, as i've already said, the things that make me skeptic about Reyes is the fact that he's not putting a lot of pressure on and is the smallest one out of the three (being 193cm/6'4" tall, he's not generally small by any means though for a LHW).
Agreed about Walker looking insanely good so far, but we'll have to wait how he fares against better opponents. I'm pretty optimistic though and i also think that he might have a really good chance of dethronign Jones in the rather near future.
Hm.. Reyes is not a power puncher by any means and it'd surely help against Jones having dynamite in his limbs, but why do you think he'd gas out against Jones? I think his cardio has looked pretty solid so far, except against Volkan maybe, but he took some damage in that fight, so it's undertsandable i think.
This. Walker is a giant for a light heavyweight and is a tall and really rangy guy as well. The reasons you've mentioned are some of the main reasons why i also think he's able to pose tons of danger to Jon. Jon really relies on his reach, but with his reach advantage being diminished to such a little number, it won't be too much of an advantage, especially against someone who's that explosive and as you've said good in closing the distance fast.
The inability to tell a lot about Walker because of his little fight time in the UFC really is an advantage for Walker, but i still think that albeit Jones is good at exposing his opponents flaws, the main reason for Jon's dominance is the fact that with his reach, great linear striking from distance and dominant clinch-game from close ranges he's a bad matchup for almost everyone in terms of striking and with his great wrestling he's been able to hang with elite-wrestlers as well so far. I think that proficient strikers his size who're both good at kicking and boxing, ideally have knockout-power and the ability to not get taken down at will from him, have the best chances of beating him, hence i've been talking about Reyes, Rakic and Walker.
