Regarding old NHB fighting, and people who claim that 1995-2000 had "cans" fighting:
The Gracies changed everything. They really brought BJJ to the forefront, which was most certainly a positive. Prior to them (Royce, really), a fighter with a wrestling background would dominate, as when you have two skilled fighters, there is no doubt where the fight will eventually end up; the ground. However, the Gracies insisted that headbutts no longer be allowed in UFC. I know this for a fact. Had headbutts been allowed, Royce would not have been able to hold guard as long as was typical for him, because one of the best tactics to use to break guard is to headbutt the fighter in the guard to create some distance to allow you to use your arms. Without headbutts, if you give up your arm to create distance in order to throw a punch, your risk ARMBAR.
