Bas was one of the first "smart fighters" who knew exactly what he needed to learn to be successful and was awesome athlete in his prime. No doubt he would of been one of the best today, the guy is the full package.
This. Bas is a very smart person/fighter. I think he would have the skills and ability to change his game according to the needs of the game. He has what it takes to have been top 5 easy IMO.
