Striking: What exactly does Nate do better? boxing? maybe but he doesn't have the power to put Tony out.. and while Tony doesn't defend his head very well.. Diaz doesn't either and he refuses to block any type of strike other then a punch.. Winner: Tony is the better more varied striker who isn't a one trick pony (the 1,2) Cardio: I hear some people talk about cardio but every fight that's gone to the 5th Nate has lost.. in fact he looked pretty gassed to me in the 2nd Conor fight. He throws a lot of punches true.. but at the expense of any real KO power. Tony went full out in Mexico city vs another beast who has crazy cardio in RDA the same guy who literally toyed with Diaz over 3 rounds.. Winner: Tony.. Nates cardio is incredibly overated.. Tony can go/throw hard for 5 rds straight.. Nate can go 5 with high volume but doesn't throw anywhere near the power other guys do JJ: Both have a lot of subs.. Tony has a far easier time of implementing his jujitsu game and has subbed much better fighters then Nate has. Winner: Tony Wrestling: No comment Winner: Tony.. Overall record/resume: Tony is on a 10 fight streak vs the best in his division outside of Khabib (who he was meant to fight).. In his last 10 or so fights Nate can barely win more then 2 in a row before he loses a couple.. Winner: Tony by a landslide Adaptability: Lastly and most important for me (basically why Nate has never been a great fighter).. the Diaz brothers point blank refuse to change the style they have.. either in camp or mid fight (when stuff is clearly not working).. they plod forward mindlessly and keep eating leg kicks/being taken down etc and just refuse to adapt. Tony on the other hand studies/trains all aspects of MMA and constantly wants to improve.. the guy has been behind often (he is a slow starter) and consistently finds a way to adapt and win.. people call the guy weird and maybe he is.. but he meticulously crafts how his training camp goes and picks out areas to improve So really why would anyone want Conor to fight Diaz over Ferguson? i say this as a Conor fan also (the boxing stuff did kinda turn me off a bit tho).
