From a technical standpoint, these two are among the tops in the UFC WW division and I really enjoy watching their styles for I believe they both possess thoughtful and skilled attacks.
With that being said, Thiago has some scary grappling and if he can circumvent Kampmann's boxing and get inside, I see him scoring a takedown and taking this fight.
