No, I meant exactly what I typed - guys that are skinny with super-long arms at higher weight-classes (LWH/HW) have traditionally never been elite power-punchers in MMA. Even if they are very elite athletes throwing power with hands is typically best for more compact fighters.
Just because he's a super-athlete doesn't mean "punching power" is an innate characteristic of innate quickness/endruance; it has to do with having "heavy hands" (i.e. higher concentration of bone density in the hands) and having larger shoulders (which have the downside of causing you to gas more if stuck in wrestling/clinch-fighting positions). It's also a stylistic choice; to throw hard you must sit-down on punches which makes you immobile; if you have the longest reach and super-quick footwork wouldn't you prefer to jab/teep/low-kick and move then throw bombs where someone can step inside and counter you?
The "longest" guy who had elite power with hands was probable Rumble Johnson and he was 78 inch reach with more muscle-mass in his shoulders/deltoids (also was a power-lifter that focused on throwing power shots to compliment his pressure-boxing game that was built around intimidating you with his striking ferocity). For comparison Jones is 84 inches with more balanced muscle-mass throughout his body. Gus has similar build to Jones and seems to have slightly more power but it seems to be style-related (i.e. boxing approach to sit-down on punches when possible instead of alternating between out-fighting with long-range strikes into clinch-fighting).
Most guys we think of as "Elite Punchers" at LHW = Rumble, Chuck, Shogun, Rampage, Latifi, Manuwa, Glover. None of them built anything like Jones - closest is Gus and when has he ever one-hit anyone? Dude had to hit Glover with like 100+ power shots and 3 flush upper-cuts in a row (plus a straight right) to finish him off.
Of course it's hyperbole for the sake of fun, sheeeiiiit.
That being said, Jones has the most elite kicking game we've ever seen on multiple levels (in the UFC/at LHW/in all of MMA).
Don't think we've ever seen somebody be able to land such a diverse array of kicks consistently against a variety of dangerous opponents while staying defensively safe for the majority of it.
And Stipe said that DC doesn't even hit that hard, even though he got dropped by a clinch strike and KO'd inside of 1 round by dem' hands....so what does it matter what one fighter says in one instance? In Gus's opinion they have similar punching power even though Jones hurt Gus mostly with elbows and high-kicks while DC hurt him with mostly with clinch uppercuts and dirty boxing??? GREAT comparison there by Gus if he actually said it....
