Ron De Rowsy was getting high praise too
Nate seems like a terrible boxer other than some fundamentals and that he enjoys it so he’s versed in it by mma standards
He has no power, no speed, slow footwork, it’s hard to imagine he’s some great boxer other than boxers praising him for his dedication to its cross-training
He’s a very good LW but very overrated and very beatable and has been inactive which doesn’t help build his case as a top tier LW and now he’s going to dabble at WW again where he’s 2-3 record and two were versus undersized Conor McGregor not true WWs
Where both the Diaz bros both shine is at close quarters. On the inside, at close range, up against the cage which is where their volume, pressure and combinations are quite formidable. To beat them on the feet you need to keep distance and continually move as they aren't nearly as good at range, against fighters with diversity of movement. Which is what you seen from Conor against Nate and Condit against Nick.
Thing is, they have iron chins and can walk through literally anything you throw at them. They have high level cardio and can set a pace few can keep up with and eventually that pressure allows them to catch up to you.
When they sense you slowing down, they smell blood in the water and turn up the pace, swarming you like sharks.
You definitely don't want to go to war against a Diaz bro. They thrive in that chaos. But, if you play a calculated chess match type of fight, constantly moving, make them chase you.. Some of the holes particularly at range like you mentioned are far more glaring. Definitely some seriously slow prodding footwork on both of them, but if they're allowed to get off on you, they can throw some serious volume and fairly technically impressive combinations as well.
But technique isn't everything. Certainly isn't the thing which allows them to be formidable in a boxing realm. It's more so all the other attributes which the Diaz bros are famous for. Iron chin, warrior spirit, don't give a fuck, insane cardio, volume, pressure, combinations.
There's a lot of guys more technically impressive than the Diaz bros in a traditional sense, but those certain attributes are what push them over the edge and make them as formidable as they can be.
Just my thoughts. I could see why the Diaz bros would be more formidable in a ring as opposed to a cage though, not being forced to chase their opponents around nearly as much would make that style far more effective.
Ronda didn't get praise from anyone other than Edmond as far as I know lol
