Just to give you an idea about how different there gyms are. Barao trains at Nova Uniao with Aldo, Torres, Marlon Sandro, Victor Riberio, Hacran Dias, Luis Ramos, Wagney Fabiano, and Eduardo Dantes. While Mike McDonald trains at Last Stand Fight Team (I've never heard of them) with nobody. This alone garantees you have no chance of winning the fight if you don't have the proper coaching and training.
I once went to a gym were the instructor was a 21 year old kid claiming to be a BJJ black belt, I spared with him and put him in a crucifix with 30 seconds, and then the kid wanted to charge me after he proved he wasn't skilled enough to teach me.
