One little technique I really liked in the first round was when Tony was landing shots on Edson from the bottom and Edson covers up, but as Tony opens up to hit him thinking he's in defensive mode, Edson smashes him to body with an elbow with his hand still defending his head. Great tactics. Around the 3.15-20 mark.
Fuck Tony can take a shot. His style is a very unique in that it simply shouldn't work. He should be getting blasted out of there. But it's just so much pressure from so many angles that guys just can't find room to breath and pick him apart for long enough.
