Again the problem is that the media puts too much emphasis on which promotion the fighter fights and not on how that fighter fights or how well their opponent fought.
For example, some of the best, most brutal, and most skillful fights I have ever seen were from unranked guys. While some of the worst fights I have ever seen were from two highly ranked fighters.
Guram Gugenishvili is the #7 HW in the world? And he is above Cain?
This is just absurd, really. Guram has only beaten two guys that have winning records, and he has never faced anybody with more than 8 fights.
The same arguement could be put up to Cain's lack of quality wins against quality opposition and have CroCop and Nog leapfrog him......even though Cain would most likely beat these two past-their-prime fighters.
