Fedor - Widely regarded as the best heavyweight in the world. Recent defeat of Arlovski to hold the Status. Once he fights in the UFC he will quial all calls to fight the best current competition.
Brock Lesnar - Too early to call him the P4P anything. Last defeated a legend and looks to avenge his only lose to Frank Mir. If he has evolved enough to avoid the submission game, he should take a walk in the park. Current: UFC HWC
Anderson "Spider" Silva - Often Highly contested with Fedor as best P4P period in all weight divisions. Most recent win over Leites, whom he obviously over matched again. Highly critisized for his last two "boring" performance. Give the man a challenge and then we will judge if he is on the decline. You can't be a P4P king if no one exists to challenge you. Current: UFC MWC
GSP - Need I say much. Amazing skill set makes him dominate all recent opposition and may only be vulnerable to a "punchers chance". Next defense over Alves, whom lost to Fitch, whom GSP destroyed. Many call for a GSP v Silva showdown. If he wrecks Alves, given Silva came in at 183 for his last fight, that may be a possible SUPER match. Current: UFC WWC.
B.J. Penn - Highly regarded as the BEST lightweight around. Kenny Florian gets an honorable mention becuase he recently "called out the master". B.J. Penn now defending his own title will get a chance to prove his reputation. My guess is Ken Flo assumes this spot. Current: UFC LWC.
Varner - Honorable mention. The WEC is combining except Bantam and Feather weights. This leaves Varner in a limbo. My guess is he will have trouble with the top guys in the UFC. Time wil tell. Last held: WEC LWC.
Mike Brown - Current WEC Featherweight Kingpin. Question? Will Faber get sloppy again in the rematch or will Brown remain the Champion on skill alone? As the Champ he last had an easy defense and looks to continue his reign. Only Faber stands in his way.
Miguel "Angel" Torres - Last, but not least on the totem pole of size. With a skill set and drive that can't seem to be matched anywhere, he destoys all comers and wages wars. No one blames this guy for boring fights and I doubt they soon will. Next up for him should be Bowles. That looks like a great fight. Current: WEC Bantam Weight Champ.
