Case in point, think about fighters in the UFC or any fighters competing in the top promotions over the years. How many fighters have shown the ability to clinch fight, execute takedowns, submit/sweep/escape from bottom, submit/control from top, all at a very high level? Damian Maia? BJ Penn? GSP was never really on his back but was likely very good from there. Mayhem Miller was actually quite solid everywhere. Jacare? Jake Shields? There haven't been many who got to show that they were very good at all of it.
