BJ beat 2 Gracies and those are meaningless, yet Saku gets praised for his wins over those same opponents while he's bigger than Penn. Saku's a WW/MW under modern rules while Penn's a FW/LW. That makes those meaningful. Ludwig was also bigger than Penn and highly ranked. Hughes came off of 3 wins and was thought to be in title contention again because he started working more on his striking at that time. The first Hughes win is not only meaningful, it's arguably the greatest win in mma history. It's the equivalent of Bisping moving up to LHW and stopping Jones in the 1st round.
