Two UFC Champions showed why they are on most people's list of the very best pound-for-pound fighters in the world by doing more than beating the competition. B.J. Penn, and especially Anderson Silva, looked like they were a different class of fighter than their opponent. This bears mentioning, as Silva fought a former champion in Forrest Griffin and Penn fought the consensus #1 contender. Silva knocked out Griffin in the first round and Penn choked out Kenny Florian in the fourth round to retain his lightweight title.
