Barao over Aldo and Tex over Machida? Interesting picks. I think both would be wildly entertaining fights and I think all fights listed have the potential to be competitive.
Barao has super impressed me thus far, Aldo IMO really has only had moments of brilliance. I watch Aldo fight Florian and am utterly unimpressed then you have the Mendes fight which was a thing of beauty I am really not as sold on Aldo as most.
Tex/Machida I look at like this Machida's big thing is he is "elusive" right, well if he is training with somebody then they likely know how to catch him, they have had hundred of rounds to figure Lyoto's game out not the 3 or 5 the guys who fight him usually do.
