Ithink Ariel Helwani was misleading in his question.
In he first round, Joe asked Evans if Rampage relying only on his punches was a weakness.
Evans responded that it made him predictable, and it makes him less that he could be. He would be better if he used more kicks and takedowns, mixing things up.
Later in the fight, Joe made a comment, that sounded along the lines of what Evans said earlier.
Ariel Helwani was basically saying that Rampage only punched, but in third round mixed things a little more up, but still relied heavily on his hands and said that Joe Rogan crticised Rampage for this.
Fun trivia: In danish "kamp" means "match" or "fight". So Martin Kampmann really lives up to his name.
