Like, if I remember correctly, Brendan (the BJJ brother) catches two different fighters (granted, one being his untrained brother) in an omoplata. In the entire history of modern MMA, how many people have been caught in an omoplata? Maybe a hand full. And this dude gets two in one tournament. There's also a moment where he gets locked in a deep rear-naked choke for about 30-40 seconds and doesn't go unconscious.
Then there's Tommy (Marine brother). Despite only ever training in wrestling (and whatever military training he received) and his trainer/father being a pure wrestling coach, he has good enough boxing and Muay-Thai(???) to outstrike and KO, supposed, world class MMA fighters with ease. Also, his wrestling(and Koba's for that matter) essentially boil down to him picking people up and throwing them across the cage like they're stuffed animals.
