"Filthy" Tom Lawlor
He scores big points for his Hulk Hogan and Dan Severan impersonations.
However, he lacks the mainstream appeal to make an immediate splash in the world's largest professional wrestling company.
His out-of-cage antics and solid wins over veterans Patrick Cote and Jason MacDonald have earned him a cult following, but that's simply not enough for the WWE hype machine to get behind.
At only 29 years old, Lawlor should dedicate the next few years to performing more consistently in the octagon and thus upping his stock.
Michael "The Count" Bisping
The self-assured, tempestuous Brit is a natural heel, especially in the U.S. market.
He's the kind of polarizing figure I can imagine getting booed out of the vast majority of arenas, yet cheered to no end by "smart" crowds in the U.K. and Canada.
That said, he is maybe one or two big wins away from a title shot.
For a fighter as serious and hardworking as Bisping, there's no sense trying out a different sport when you could conceivably be the one to dethrone the great Anderson Silva someday.
Dave "Pee-Wee" Herman
Youth, brashness and size are on his side, but he's still quite unknown.
I admit, there's something amusing about his claims that jiu-jitsu doesn't work. Too bad punching definitely does, as "Pee-Wee" has lost his last two fights by knock out.
He's a forgettable 2-1 in the UFC.
Everyone's least favorite eye-gouging ignoramus.
Koshcheck's been bested by welterweight kingpin Georges St. Pierre on two occasions, and his decision loss to Hendricks knocked him further out of title contention.
A different career path would be wise, but we're talking about Koshcheck here, a person conceited enough to think professional wrestling is below him.
More significantly, Koshcheck is inarticulate and somewhat small in stature, so there's little reason for WWE to pick him up.
"Suga" Rashad Evans
His showboating, chiseled physique and participation in several big-money fights could get him through Vince's door.
There's no doubt that Jon Jones outclassed him and left Evans' relevancy up for debate, so a departure from MMA can't be ruled out.
But until Rashad Evans tries the middleweight division on for size, there's really no reason for such a well-rounded athlete to hang up the gloves.
Diaz is skinny enough to receive a push comparable to that of Colin Delaney if he were ever stoned enough to sign a long-term contract with WWE.
That doesn't mean a one-off fight ala Floyd Mayweather, Jr. couldn't work. Diaz would get a sick payday.
WWE and UFC fans alike would get a chuckle out of Diaz's hooligan mumbling and Stockton slapping.
Diaz is notoriously averse to the media, but if he were smart, he'd sign a contract with WWE to defeat one of their Superstars on pay-per-view.
Otherwise he's a dead subject until his suspension ends in February 2013.
He's not much of a talker, but the 'Reem is enough of a horse devouring mutant for Vince McMahon to overlook that.
Could he pass a Wellness test? Sure. I mean, Batista did.
But I don't even want to think of him exiting the UFC until we see how Junior Dos Santos deals with the Dutchman's fire power.
His edgy demeanor and colorful verbiage could make him a believable bad boy wrestler.
Yet I wouldn't bet on it.
Chris Leben has made a name for himself by absorbing and throwing wicked shots, but that doesn't have the same kind of wow-factor in matches we know consist of feigned attacks.
