In no particular order:
• Zuffa, the parent company for UFC and WEC, now promotes the No. 1 fighter in seven weight classes -- the lone exception being flyweight, which isn't included among the divisions featured by the Las Vegas-based powerhouse. Emelianenko, 33, was the lone hold out before tapping June 26 to Fabricio Werdum. In his place steps UFC heavyweight champion Brock Lesnar, who willed his way to victory July 3 with a second-round submission against Shane Carwin.
• For the first time since Mark Coleman captured the Pride Grand Prix 2000, an American is considered the best big man in the sport. That won't change through 2010; Lesnar is slated to take on Arizona's Cain Velasquez next.
• There's long been an argument about whether or not heavyweights deserve a place at the P4P table. Emelianenko was, for the most part, considered a Top 3 fighter in the world regardless of weight after dismantling Antonio Rodrigo Nogueira in '03 to capture the Pride heavyweight title. There he remained, on my list at least, for two reasons: dominance against his peers, and the level of skill he used while surviving unbeaten over 28 fights. Undersized and expertly skilled is a solid formula to gain and hold a place among the 10 best fighters in the world regardless of weight. Of course, losing the way he did to Werdum (a 69-second loss via triangle choke) unquestionably drops Emelianenko from the rankings. Where we've seen other P4P fighters lose this year and remain in the high-rent fraternity -- B.J. Penn to Frankie Edgar; Lyoto Machida to Mauricio Rua -- there isn't any logical way for Emelianenko to remain simply because Werdum doesn't deserve the recognition. And neither does the gigantic Lesnar, who seems to be the antithesis of what "pound-for-pound" signifies. I can't think of any fighter more reliant upon his size and strength. Of course, should he pull off a couple more finishes against Cain Velasquez and Junior dos Santos -- particularly if they come with the kind of technique that forced Carwin to quit -- it would be worth reexamining.
• When Jake Shields inevitably signs with the UFC, Zuffa will own 90 percent of SI.com's pound-for-pound space. The lone holdout: third-ranked lightweight, Strikeforce champion, Gilbert Melendez, who joins the list after Emelianenko's departure. Lightweight is the only division featuring three fighters on the P4P list.
• I won't go so far as to suggest this the first time I had a tough time piecing together a division, but I can definitively say this is the first edition that it felt nearly impossible to accurately rank welterweight. One through three is easy. Georges St. Pierre is dominant. Jon Fitch hasn't lost to anyone but the 28-year-old Canadian champion in eight years. And Thiago Alves solidified the third spot a long time ago. But from four to 10, it's u-g-l-y. Why? Parity. Fighter A has a solid win against Fighter B, who defeated Fighter C. What then? Well, Fighter C beats Fighter A and the whole thing comes tumbling down. Take Martin Kampmann (17-3), Paulo Thiago (13-2) and Josh Koscheck (15-4). Kampmann jumped up to No. 4 after a dominating decision win against the similarly ranked Thiago, who knocked out Koscheck last year. Makes sense. Yet things get particularly muddled because Kampmann was knocked out in 2009 by Paul Daley (ranked No. 10). And Daley just happened to drop his last fight on points to Koscheck. Fun.
• Three 1-vs.-2 bouts are scheduled between Aug. 7 and Aug. 28. That's quite a stretch. Anderson Silva's UFC middleweight title is at peril against Chael Sonnen on Aug. 7 in Oakland. WEC bantamweight champion Dominick Cruz will attempt to defend his belt against Joseph Benavidez on Aug. 18 in Las Vegas. And Frankie Edgar gets the chance to prove his win over B.J. Penn last April wasn't a fluke, when the UFC lightweight title is up for grabs in Boston on Aug. 28.
