Normally id say 'we'll have to agree to disagree', but i value your opinions so I want to try and change them ( a bit).
At the time of the early UFC's those competitors admittedly looked like bar room brawlers compared to the rounded athletes there are today. But at that time alot of those guys were trained fighters at their own artform. Ground fighting was not really heard of in America and was the reason Royce won 2 tournaments in about 6-7 mins total.
Just because these other figters were clueless on the ground is not Royces' fault.
Regardless of style, for a small man like Royce to beat Kimo was groundbreaking.
The impact Royce had on the MMA world was massive. BJJ and the Gracies took Martial Arts by storm.
He was the first to mould the sport...
Severn added more with werstling... then Coleman with GnP.. (and frye a bit).. then Couture with his 'dirty boxing' when he beat Vitor.
BJJ is still a huge part of the sport today..all started by Royce.. a fighter without it is in trouble.
Therefore he is a legend
