1. Best. Lightweight. Ever.

If there was ever any doubt (and there shouldn't have been in all honesty), BJ Penn made it abundantly clear within the first 45 seconds of his fight with Diego Sanchez that he is simply on another level than everyone else at 155 pounds. In each of his last two title defenses, we've heard the build up of the challenger being a great test for the champion, and each time, said challenger was thoroughly dismantled by Penn. There isn't a lightweight in the world who can hang with Penn, and there hasn't been one better in the history of the sport. Not Aoki, not Pulver, not Gomi, not anybody. BJ Penn is the best lightweight ever and one of the greatest fighters of all-time.

2. Now What?

Each of his last two opponents were supposed to have the skills to be a challenge and potentially end the reign of the kid from Hilo. Both those men were sent home with their tails between their legs. After dominating Diego Sanchez last night, there isn't a sole lightweight who could honestly challenge BJ Penn remaining in the UFC. Not because there aren't some talented fighters in the division, but because Penn is a transcendent talent. Where things go from here is anybody's guess. Personally, I have no interest in seeing BJ Penn move up to welterweight, as Dana White recently said the lightweight champion would have to start at the bottom and work his way to another title shot.

Joe Rogan tossed out Shinya Aoki's name last night, but that isn't going to happen. In addition to being contracted to DREAM, if "The Tobikan Judan" is fighting in the United States, it will be with Strikeforce. And let's be honest: Penn would smash Aoki. Keep dominating and defending the belt; a year from now, Kenny Florian will be due for another title shot and then we'll see if the third time is the charm.

3. Even in a Bloody Defeat, Diego Sanchez Impresses

For all the jokes and ribbing aside - from the YES! routine to the greatest mean face in the history of mean faces - Diego Sanchez is one tough kid. Less than a minute into the biggest fight of his life, he was rocked and made painfully aware of what a long and painful night it was going to be. But he just kept coming and coming and coming and coming. His unbreakable spirit looked broken at the start of each of the championship rounds, yet Sanchez kept walking out to the center of the Octagon. We've seen fighters, including Penn himself, call it quits and give up, but that just isn't a part of Diego Sanchez' makeup. While he was completely dominated and left beaten and bloody, Diego Sanchez showed the heart of a champion and deserves some recognition today.

4. "Water is Wet"

Yes, Frank Mir quickly disposed of Cheick Kongo, connecting with a big punch before putting the French kickboxer to sleep with a guillotine inside of 90 seconds. But going into that fight, who didn't know that Frank Mir was going to submit Cheick Kongo pretty damn quickly? Mir is a great submission fighter and Kongo has a pretty horrible ground game, so Mir earning a win by submission is about as shocking as learning that water is wet. Now, what was impressive and a new development stemming from this bout was the recreated Frank Mir. Holy weight training, Batman! While I would...
