Cliffs: Tony focuses too much on being wild, unpredictable and unorthodox instead on his fundamentals. His lacks fundamentals and it's gets worst with age.
It sounds great when you say that while someone's getting his shit pushed in and it sounds right.
However, I don't necessarily agree that's why he lost. Fundamentals doesn't help you get up from a superior BJJ player who got top position on you. Fundamentals doesn't necessarily help you from being able to fend off takedowns.
This isn't boxing where staying with your fundamentals, or stepping away from it, could come to bite you in the butt, like Roy Jones JR, you know when the speed and reflex isn't there.
Even if Tony had sound fundamentals, it wouldn't have helped him much better with a superior BJJ guy on top of him, nor do I think it would have helped Tony from fending off takedowns.
I think it's just Din Thomas trying to sound smart and saying the things that rounds right when Tony's getting his shit pushed in.
Tony in his prime was dangerous everywhere. He had heart, he had cardio, he had power, and he has submissions threats. He was most definitely unorthodox, but he wasn't always THAT unorthodox, from TUF days and all.
Tldr, I think Din Thomas just talking out of his ass, and Tony doesn't have bad fundamentals, he just lost to a better fighter.
