Personally I don't like Mauro, he sounds like a gameshow host to me and his voice is WAYYYYYYYYYYYYY overdone. I've been in the "talking for a living" business for a long time, and I can tell you all quite matter of factly, that be pushes his voice.
How he sounds is NOT natural, and in my opinion (And that of some of the best program directors in North America) a natural voice will go 100 times further in the business than a "pushed" or "forced" voice.
With that being said, I liked Quadros and Bas much better.
When the UFC LHW champion is sitting next to you AND he is Randy Couture, you do not say that Pride has the best fighters out there. It makes you and the orgainization you are representing look stupid.
I thought it was funny when Bas called Mauro on his Nogueira mistake.
Randy is simply the best commentator out there. He and Bas made a great team. I hope he is hired as a commentator by one of the organizations when he retires.
