I don't think he hates groundfighting, but what he considers boring fights. The fight in question here, I thought it was an exciting, hard fought battle.It was also the kind of fight that got Fitch, Okami, Shields, and others cut.
Dana loves to see damage, what he calls 'absolute wars', and finishes. Plus fights on free tv in general needto be exciting to draw new fans in. That's why they only show performance highlights on the first episode if a fight goes the distance. I wouldn't go as far as to call Dana a Just Bleed-guy, but he is a promoter, and that's why shits on fights like this.
Never will I ever be fake, never will I follow
