Anderson's isn't that beatable. Jacare is probably one of the top 3 BJJ guys in the world, but MMA is a totally different game. Look at Marcelo Garcia. He was beating guys in BJJ that were 2-3 weight classes above him. In MMA he lost his first match from a cut and most of the 1st round they were on the ground (hasn't had fight #2 yet).
It's one thing to be a great BJJ guy, but you need to evolve your BJJ game into BJJ for MMA. It's tough trying to sink in a triangle choke. Now try putting on a triangle while the guy on top is raining down fists in your face.
BTW, I would love to see this fight
