"The sport has evolved" cliche is always laughable to me. People heard this SO many times on commentary over the years that they just repeat it themselves despite having ZERO evidence to back up their claims.
These comments made much more sense in the mid 2000s when we had "old vs new" match-ups like Fedor vs Mark Coleman, Rich Franklin vs Ken Shamrock, Matt Hughes vs Royce Gracie, etc where one-dimensional pioneers were defeated by a well-rounded new breed but the development of the sport is nowhere near as rapid now than it was back then when cross-training was still a new thing.
Remember when Rory Macdonald was praised as this "next generation fighter" because he was training in all disciplines from the very beginning specifically for a career in MMA? Yeah... his UFC debut was 16 years ago FFS... I think the whole "he can win the fight in multiple ways" hype has cooled off quite a bit in that time period, don't you? lol
If anything, many fighters in modern day are even LESS well rounded than they were a decade ago. It's no shocker that the few competent grapplers in the sport look absolutely invincible considering 90% of ranked fighters are one-dimensional strikers who have just enough BJJ experience to not get submitted but are absolutely hopeless in terms of scrambling or god forbid being an actual threat from guard.
Fighters get old. Their reflexes slow down, their ability to take damage lessens... but it doesn't mean their skills are suddenly obsolete and that the current fighters in their prime are automatically better. Have we suddenly seen new crazy submissions and strikes being invented on every card that would make Mighty Mouse Johnson look like Tank Abbott by comparison? I was not aware of this
Styles make fights... regardless of era. Do you really think a long lanky striker like Conor McGregor would have a prayer in hell of stuffing a takedown from a prime Sean Sherk? lol Would Jack Della Maddalena piece up GSP because modern fighters are just
better? LOL
"The sport has evolved" is just another lazy cliche spewed by the UFC in a desperate attempt to sell PPVs. If you catch yourself saying this post 2015... just stop. You are hopelessly brainwashed by the hype machine
