Believe it or not, there are still fans and even pundits who believe a superfight pitting UFC Welterweight Champion Georges St. Pierre against Middleweight Champion Anderson Silva could happen. Someday.

Famed boxing trainer Freddie Roach, who has worked with both men and continues to work closely with St. Pierre, has some cold ice to toss on those hopes.

"Anderson Silva hits harder (than Georges St. Pierre) because he's a lot bigger. But Georges is also a good puncher also. But the thing is, size wise, I think Anderson's a little more fluent at this point. He's a lot bigger than Georges, of course. That's why I don't think that fight, they've been talking about that fight happening, I don't think it will happen. I've talked to Georges about it and (Silva is) just way too big."

Well, gee, that's just downright logical.

Traditionalists, of course, will decry this explanation for why the fight will never come to pass. After all, Royce Gracie ran through all comers in the old days, be they 150 or 250-pounds.

That's ignoring the obvious point, though, that the game has evolved to a point in which size is one of the few advantages modern mixed martial artists have left. With extensive training and practice, not to mention a proven track record of application in the cage, it's hard to tell who would have the advantage in a fantasy match-up between Silva and St. Pierre.

Until one considers their respective size. And therein lies the rub. If Roach is to be believed, even "Rush" knows it may not be worth potentially tarnishing his legacy in an attempt to take down a much bigger foe, even if it would make him the greatest pound-for-pound fighter who ever lived.

It's just too bad, really. There is no bigger fight to make right now or in the history of the game than this one. Oh well. Hear more from Roach after the jump.
