Well I wouldn't want to get personal here, but you've shown a lack of respect so I guess I'll take the gloves off.
First of all- I question the judgement of anybody in a situation when given by somebody who's never been in said situation or another one like it.
Second of all, calling Matt Hughes an "ass" accomplishes nothing.
If you want to say "Walks like a duck, talks like a duck, is a duck." Then I guess what you mean to tell me is that Matt Hughes is one of the most highly accomplished fighters in the history of MMA, has trained men at one of the most successful camps in MMA, and has vast amounts of coaching experience/WINNING experience over Matt Serra.
Recall when everyone thought Hughes was a total "ass" in Season 2. Then Rashad Evans had to be cornered by Matt Hughes, even though Matt had made himself an "ass" specifically to Rashad Evans. Evans wasn't happy about the decision, but after the fight was over (which he won, btw) he was ecstatic about Matt's coaching and said he learned a lot of great things. Or recall Mac Danzig's own little "speech" after he won that fight that aired yesterday. When he said he couldn't be happier to be a part of Team Hughes.
Read Mac Danzig's own blog in which he constantly talks about how Hughes was tough on the show, but in retrospect he learned many great things and now he sees why Matt did the things he did.
Point is- there's plenty of facts out there by people who were much more closely related to the Matt Hughes situation that show Matt was, in fact, a great coach. Some NOBODY on the internet calling out one of the greatest fighters in the history of the game on something he is not even a part of just reeks of an outright disrespect to me. Sure, it's an opinion, and as stated before, there's no way I can sway you.
I just urge you to take into consideration the fact that you see maybe a total of 10 minutes of actual Matt Hughes each time you watch that show. And I also urge you to be aware of the fact that those 10 minutes you see are hand picked by the show's producers/writers in order to display a certain attitude so as to generate controversy. Controversy that you, apparently, are nothing but happy to buy into and judge a man by. I take people by what they themselves accomplish/show me. Not by what somebody shows me through their own vision which is clouded with personal motives/prejudices.
I guarantee you that if you take every single fighter that was on Hughes' team and ask them if they learned anything or took any valuable lessons out of training with Matt Hughes not a single one of them will say no. Then again, you know so much about leadership and training people that I'm sure you wouldn't learn anything from one of the most successful men in the business, right?
