UFC on Versus 4 is set to go down this Sunday night (June 26, 2011) live on the cable television network emanating from the CONSOL Energy Center in Pittsburgh, PA.

In the headlining bout, Rick Story looks to make a serious statement in the welterweight division when he steps up on short notice to replace Anthony Johnson against former middleweight number one contender Nate Marquardt.

And "The Great" is probably staring in "Horror" at the current betting line, which pegs Story as the -130 favorite.

That leaves Marquardt as the +110 underdog, which may have resulted from the "X-factor" surrounding his first cut to 170-pounds in addition to Story's blistering six-fight win streak.

Are the oddsmakers calling it like they see it? Or playing it safe? Take a look at how these two welterweights stack up after the jump and decide for yourself.
