If he won the fight without using TWC at all, then the fact that he also trains TWC is irrelevant and claiming it as a win for TWC is stolen valor from his other coaches that trained him to win the fight with functional methods like BJJ, and the effort he put into that training.
That he won his fight without using TWC is supposition on your part, and manifestly biased supposition, based on two action photographs.
Ethan's principal coaches are pictured with him below: Tracey Aldridge, and Brent Duggan. Both Red sashes in TWC under Rick Spain. They all live in a small town called Ulverstone on the North Coast of Tasmania. Not surrounded by famous MMA gyms or coaches. Tracey owns the gym where all are coaches. Ethan is a gold sash in TWC. This is a full time gym teaching Wing Chun, BJJ, kickboxing (for competition) and MMA.
Anyone who does BJJ and MMA will have trained with coaches other than those at their home gym occasionally (I've done Pedro Sauer, Steve Maxwell, JJ Carlos and Rigan Machado, etc. etc.) but Ethan's main coaches in all aspects were Tracey, Brent, and earlier, Tracey's ex, Stuart Clayton. These people are deeply committed to their training and their students
Just because you can't imagine ever having the personal resources to pull off anything like this, doesn't mean that more capable people can't do it.
Stolen valour? You have no idea what you are talking about. You insult people who have achieved far more in martial arts than you ever will.
You are desperate to find holes in this presentation. None exist.
Look at yourself and what you are doing and see how nastily and disingenuously you are behaving. Why? How do your actions help you become a better martial artist or human being?
