Back in 2009, when Georges St-Pierre met B.J. Penn for the second time, they were arguably the two brightest stars in the UFC's growing constellation.
St-Pierre, the UFC Welterweight Champion then and now, was well on his way to cleaning out the 170-pound division. Rush had rattled off consecutive victories over Josh Koscheck, Matt Hughes, Matt Serra and Jon Fitch to claim, then defend the belt.
Baby J, then the UFC Lightweight Champion, hadn't tasted defeat in three bouts since dropping down to dominate the 155-pounders. The Prodigy was on a three-fight win streak that had also seen him claim, then defend his belt.
Both guys were superstars, both were champions and each man appeared to be the only legitimate challenge on his opponent's horizon. They almost had to face each other lest the fans eat other in their increasingly frenzied demands.
I mention that infamous matchup because UFC President Dana White and company are steadily approaching another such tipping point.
Despite the brass's application of the brakes whenever and wherever possible, the moment when GSP must face UFC Middleweight Champion Anderson Silva is coming. Barring a surprising loss by either pound-for-pound kingpin, simple process of elimination seems to dictate the icons would fight in late 2012-early 2013 at the latest.
Which got us thinking...
Obviously, the UFC can't arrange a superfight every year—the stars don't align that often. White, Joe Silva and the puppetmasters can, however, give the masses one or two dream matchups per annum. To prove it, here are 15 such pairings that should have any true fight fan drooling.
Just keep it off the keyboard.
