Two gifted grapplers, each in his early 20s, each hungry to assert himself at 170. For three rounds, Sanchez and Parisyan tumbled around the Octagon -- a grapplers delight -- strong takedowns, huge throws, vicious ground and pound, combined with wild, meaningful exchanges on the feet. An all out-assault on the senses for 15 minutes.
