Yeah but in the early days the guys he beat just walked into subs, guys are way more skilled now. There is a reason no champion out there right now is known for their ju-jitsu over everything else they do, the sport has evolved. The best guys are either wrestlers or strikers now pretty much. If you find yourself on your back in the UFC now, it is not a good spot to be in. A lot of guys have great ju-jitsu and keep themselves from taking any damage on the ground (think Silva vs Sonnen) but not many really do damage from the bottom these days like they could back then.
You make good points.
