When news surfaced that world jiu-jitsu champion Rodrigo Comprido Medeiros would be helping Brock with his BJJ, skeptics doubted and questioned how much Brock would actually learn. Well, let’s be realistic I’m sure we weren’t gonna be seeing Brock pulling off flying triangles or 50/50 guard sweeps, but what has happened is, Brock seems to have game plans on the ground. From his second beat down of Frank Mir where he controlled Mirs half guard to his recent submission victory over Shane Carwin with head and arm choke. It looks like Brock is starting to pick up the jitsu… Maybe we will see him one day at an ADCC or No Gi Mundials or Grapplers Quest? Who knows… I just know it would suck to be in the absolute division with him.
