Just after Erick Silva dropped Brown with the body kick, took his back and went for the RNC, I was like "Erick is gassing himself out and is gonna get finished". (I had Overeem/Browne and Carwin/Lesnar flashbacks). I didn't think he would survive 2 more rounds tho, Erick is tough as hell. Regarding is cardio, I don't think it's as bad as people think. In my opinion it's more a question of bad management of his energy. He spend to much of it trying to get that submission.
