People are always talking about Sonnen's mediocre sub defence, that he needs to get decent sub defence, etc. Based on what? In the last four years he was submitted by Paulo Filho, Demian Maia and Anderson Silva. All legit bjj black belts. Paulo Filho is a bjj stud, Demian Maia one of the best bjjers in MMA and Anderson a solid black belt. He sat in Anderson's guard for +20 mins without ever being in clear danger. Only towards the end, when he was tired and cut, did Anderson managed to sink in the sub. He manhandled Marquardt who is a 2nd degree bjj blackbelt, staying in his guard for a lot of the fight. Clearly the guy has learnt a lot of sub defence over the past few years. He trash talks bjj, but if he didn't train it he wouldn't be able to dominate legit black belts the way he does. Thoughts?
