History hardly on Tyson Fury's side

Taken at face value, Tyson Fury's challenge of Cain Velasquez is pointless because we already know the result.

Still, even if the callout is self-serving, even if it's designed to drum up interest and a payday, you have to admit there's something admirable about a talented boxer, early in his career like Fury, loudly challenging the best heavyweight mixed martial artist to a cage fight. Maybe someday Fury will suffer through getting what he wished for, and we’ll suffer for having watched it happen, but you better believe his moxie won’t go unnoticed.

Think about the 24-year-old Brit’s task. Almost everything related to boxing in an MMA contest is altered from its sweet science roots.

Spacing. Stance. Footwork. Balance. Hand position. Timing. And, most notably, what’s OK when fighters tie up. Boxing, of course, features its share of clinching. If Fury somehow talks his way into a fight against Velasquez, he'll need to remember that MMA referees don’t usually call for breaks so quickly.

Can we agree that the only thing less likely than Chael Sonnen beating Jon Jones would be Fury stalemating Velasquez in the clinch? The cold, hard truth is Fury couldn’t do anything other than get tossed on his head or eat a knee or take an elbow or get rag-dolled to the ground.

We know this because MMA’s practice-makes-perfect evolution proved it true. Examples of grapplers fighting strikers inspired a new paradigm, one that dictates the world’s baddest man is a mixed martial artist, not a boxer, kickboxer or anything else. Floyd Mayweather Jr. is brilliant inside a ring. However, competing in a locked cage under MMA rules would carry the effect of kryptonite.

Let’s not forget the ways in which Randy Couture was kind to James Toney almost three years ago. The immediate risk-nothing takedown. Guard passing without strikes. Multiple choke attempts. It might not read this way, but you better believe “The Natural” was being nice.

For his trouble, Toney made off with a big check and not much damage to his head or ego.

So we’re clear: If they fight, no one should expect Velasquez to be so gentlemanly with Fury. He probably won’t more than attempt like hell to end the fight, which is easy to envision. Like when "Judo" Gene LeBell submitted boxer Milo Savage. The legendary LeBell held nothing back during three plus-rounds until he choked out Savage in the first televised MMA prize fight in 1963.

Reports suggested Savage was unconscious for up to 20 minutes, which must have shocked the 39-year-old ex-contender’s handlers since they thought he was a shoo-in to score a knockout.

Thirteen years later in Tokyo, LeBell played part in perhaps the most infamous boxing-MMA spectacle, serving as referee for Muhammad Ali's match with Japanese pro wrestling icon Antonio Inoki. Held under modified rules that limited Inoki, the contest was carried back to the States via closed circuit.

Whether or not it was a legitimate bout (there’s a debate) doesn’t mean much when it comes to lasting value. The spirit of it all inspired Sylvester Stallone to include a scene in "Rocky III" featuring Balboa against a giant pro wrestler (Hulk Hogan’s “Thunderlips”) in what was portrayed as a sincere brawl.

Spectacle was reason enough for Rorion Gracie to challenge Mike Tyson to a match to the death for $100,000. This was prior to UFC 1, which succeeded well enough on its own as a vehicle in spectacle creation.

The Tyson escapade never happened, but if it had, you bet the world would have watched. As an understudy, Art Jimmerson looked silly wearing one glove while tapping to Royce Gracie. To no one’s surprise, the moment didn’t carry much weight culturally, yet the message was clear again. Boxing, your father’s combat sport, is mostly worthless against someone who doesn’t want to box.

From time to time, boxers stood up for themselves. Ray Mercer had his moment, knocking out former UFC champion Tim Sylvia. The experience, however, is primarily a lesson in futility.

Take for example the "King of the Four-Rounders," Eric “Butterbean” Esch. After 25 professional MMA bouts, he owns a plus-.500 record -- respectable despite some embarrassing efforts. But to get an accurate picture for this sideshow boxer’s adventures, all you need to do is revisit his first MMA attempt. Hovering near 400 pounds, “Butterbean” tapped when 155-pound Genki Sudo scurried around him like a squirrel before slapping on a leglock.

These are different sports.

There is more than enough evidence to support that.

But this fact hasn't stopped a young boxer from rattling his sabers to prove a point (and draw attention and a solid payday).

What might make this boxing/MMA adventure different from the rest? The commendable fact that Fury is angling to face the current MMA heavyweight champion. The boxer should be lauded for aiming so high.

And sufficiently warned.
