For being so easy to take down and control? I guarantee that Curtis Blaydes wouldn't have been so eager to take down someone like Fabricio Werdum, nor would he have controlled him like that so easily. Blame fighters for not training TDD and BJJ, not the wrestlers for being able to implement their style. No one is looking to take down and control guys like Maia, Burns, Oliviera, Ortega, Werdum, Ferguson, etc. Be like those guys if you don't want to be taken down and controlled. Blame fighters like Volkov for being helpless on the ground instead. Its his own fault.
