Yeah that's not making sense, Aoki/Penn flipped. Arlovski wasn't a P4P fighter but was a top ranked heavyweight. Dan Henderson and Rich Franklin were also top ranked middleweights before Silva made them look like shit. GSP shouldn't leap over Fedor and Anderson because he fought a smaller fighter who showed he didn't belong, IMHO.
up until GSP's dominance, BJ Penn was ranked top 4 in the P4P rankings and considered better than anyone Silva or Fedor has faced in the last 3 years. GSP has dominanted his weight division and now a top P4P fighter and made him look out of his league. That deserves consideration IMO.
