UFC 123 featured Quinton "Rampage" Jackson and Lyoto "The Dragon" Machida as the brightest names in neon lights, but the rest of the card ended up stealing the show. Unfortunately, the judges grabbed a large share of the limelight which is never a welcome addition.
But so it goes.
With his split-decision victory over Machida, Jackson has reasserted himself in the light heavyweight pecking order, even if it's simply a more solid foothold for a rematch against the Dragon. Additionally, we saw an impressive performance from B.J. Penn in the rubber match of his triumvirate with Matt Hughes, George Sotiropoulos turn some heads in a battle against the American version of himself Joe Lauzon, Phil Davis add another name to his resume and a couple fresh faces make a stir.
Now that the dust is settling, let's take a look at 20 lessons learned from the action in Detroit.
