Honestly, I think a lot of "MMA Fighters" have taken the more brawler route and it's showing. There's a reason guys like Silva and Fedor dominate, they do so because they stick to their training and they don't fall into the whole catagory of "I am going to rush in and punch this dude real hard and hope that works" which as we can see is becoming more and more common.
In some cases it works, look at Brock, but in others, you run into someone who doesn't stray from the gameplan, and doesn't play their opponents game.
I will agree with you that Griffin isn't the worlds greatest martial artist, however, it is a serious contender and the former champ, tonight he learned what happens when someone won't change their gameplan to yours.
I hated seeing it go down that way, I think everyone loves Griffin, he's as blue collar as it gets, he's a tough guy, but tonight showed what happens when MMA meets Brawling :(
