At UFC 109, a battle of legends will take place between two true pioneers of the Ultimate Fighting Championship.

For the first time in the 17-year history of the organization, two current UFC Hall-of-Famers will collide inside the Octagon.

While Randy Couture and Mark Coleman have both accomplished extraordinary feats in their respective MMA careers, fans can't help but feel a bit cheated that it took over a decade for this fight to come together.

The pair was originally scheduled to meet at UFC 17, back in 1998, but a Couture injury forced the cancellation of the bout.

Had that fight taken place, Couture would have been defending his heavyweight belt against Coleman who defeated Dan Severn to become the first UFC heavyweight champion.

Fast forward 11 years: a 47-year-old Couture taking on a 45-year-old Coleman isn't exactly being viewed as a "must-see" headliner.

The argument can be made that both Couture and Coleman have the athletic ability and competitive drive to continue to perform at a high-level, but fans aren't expecting the same pace from the fighters that they possessed in their prime.

Does this mean you shouldn't shell out 50 bucks to order the event on Pay-Per-View?

Absolutely not - In fact, you might be surprised with the outcome of the matchup as it may turn out to exceed your expectations.

Just because a fight is taking place past its prime doesn't mean it's not going to translate into the thriller you dreamt of when you thought of the bout years ago.

Let's take a look at seven UFC fights that would have been seismic if they happened sooner; some of them went down in history books as unforgettable wars, while others turned out to be just average or below that in their outcome.

Rich Franklin vs. Dan Henderson: UFC 93

Before getting his face smashed in from the vicious knees of Anderson Silva, Franklin was the undisputed champion of the UFC's middleweight division.

During the Franklin-era, fans fantasized of a battle between "Ace" and PRIDE champion Henderson to determine which organization's title holder was truly the best in the world.

They would eventually spar in the Octagon, in the UFC's first trip to Dublin, Ireland, but in a non-title affair.

With Franklin losing his title in devastating fashion to the aforementioned Silva three years prior and Henderson failing to capture UFC gold in his bouts against Silva and Quinton Jackson, the attraction surrounding this fight has lost much of its lure.

Nevertheless, the fight was still glorified as a dream matchup and turned out to be a closely contested bout with Henderson earning the victory via judge's decision.

Chuck Liddell vs. Mauricio "Shogun" Rua: UFC 97

From 2004-2006, UFC fans considered Liddell to be the baddest man on the planet.

With seven consecutive knockout victories under his belt, "The Iceman" seemed destined to fulfill his legacy as the king of the light-heavyweight division.

But while Liddell dominated inside the Octagon, another light-heavyweight wrecking machine was steam-rolling through the opposition in PRIDE.

"Shogun" Rua was ranked No. 1 in the weight-class, and with decisive victories over "Rampage" Jackson, Ricardo Arona, and Alistair Overeem, it was easy to see why.Still, UFC fans weren't convinced that Rua would stand a chance against their beloved Liddell.

If the fight would have taken place in 2006, it would have been promoted as a battle between the two...
