It has been said time and time again: not only is it hard to actually get a tryout and a contract with WWE but if a wrestler is talented and lucky enough to get hired, the work they have to put in to become (and stay) relevant is substantial.
Just like major sports teams draft player busts, so too does WWE hire some people that maybe weren't made for the wrestling industry. It was very apparent in the Ruthless Aggression Era when so many wrestlers became superstars, and others became just an entry in trivia lists.
10 Jackie Gayda
It's unfortunate to have to include Jackie Gayda here, as she actually had the potential to succeed. The problem was, WWE pushed her way too quickly before she was ready to properly compete.
Gayda was way too green when she got her run. While she was the co-winner of Tough Enough Season 2, she was rushed to in-ring competition, where she performed poorly. She found some marginal success as the manager of Charlie Haas (her husband) and Rico's tag team.
9 Mordecai/Kevin Thorn
Here's an extra little piece of trivia for you: Mordecai and Kevin Thorn were the same person. One character was a religious fanatic who wanted to save fans from their sins, while the other was a vampire introduced in WWE's ECW.
Neither gimmick succeeded. Mordecai was supposed to be some weird reverse-Undertaker, wearing white and talking about saving people, but ultimately being a heel. Kevin Thorn was a Gangrel knockoff, who failed to make an impact alongside his manager, Ariel.
8 Paul Burchill
Whether he was a pirate, William Regal's protégé, or Katie Lea's brother, Paul Burchill never managed to win over the crowd. As fun as it was, for like, a second, his pirate gimmick just couldn't be taken seriously.
It should have done him good do team up with Regal, but that didn't materialize either. Burchill was eventually paired with his storyline sister, and the two were very awkward together. Three strikes and you're out, as Burchill was released in 2010.
7 Rosa Mendes
Rosa Mendes had a long career in WWE, which is surprising considering she never really left any sort of lasting impression. She was a Divas Search contestant who was signed to a WWE developmental deal.
Mendes eventually made it to the main roster, which she clearly wasn't ready for. She started a storyline with Beth Phoenix, before being moved to ECW. Rosa managed Primo and Epico Colon during their WWE Tag Team Championship reign, before announcing her retirement from wrestling in 2017.
6 Vito
Vito's dress gimmick reportedly came about as punishment for his poor attitude backstage. He embraced it, but it was unfortunate how this act was portrayed in WWE as a means to gross out his opponents.
WWE didn't really try to give him anything else to work with. Besides the dress, Vito was too generic for anyone to really remember, and he was thus released soon after.
5 Heidenreich
Heidenreich was a classic Vince McMahon heel: a big dude who couldn't perform well in the ring. Sure, the gimmick wasn't original, but it was strange enough to work for a bit until he started reading poetry and threatening Michael Cole backstage.
His feud with The Undertaker was a dud, and he somehow ended up as a member of the Legion of Doom alongside Animal, even winning the Tag Team titles.
4 Deuce & Domino
This is a classic example of what Vince McMahon likes in his tag team division: over the top, silly gimmicks fans can boo and laugh at. While Deuce and Domino did what they could with the poor material they were given, even becoming Tag Team Champions for a second, ultimately nobody cared about greasers in wrestling.
Their manager, Cherry, was also an inexperienced wrestler whose in-ring career never took off.
3 Ted DiBiase Jr.
It's a shame Ted DiBiase Jr. didn't have the intangibles and that ever-elusive "it" factor. He was part of a stable in Legacy and won some gold during his short wrestling career, but that's about it.
There was nothing particularly bad about DiBiase Jr. He was just fine, and fine is not enough in the WWE sometimes, even if you're the son of a legend. He didn't do enough to make wrestling fans care, even though his biggest programs involved Randy Orton, Shawn Michaels, and Triple H.
2 Muhammad Hassan
Talk about a case of wrong place, wrong time. Unlike most of the entries on this list, Muhammad Hassan actually had potential: good look, decent in the ring, great on the mic, and a character that worked. It was refreshing that he was a well-spoken American talking about injustices and not a generic foreign heel.
Unfortunately, WWE didn't have the tact to deal with such a complicated gimmick and instead resorted to terrible clichés and stereotypes that ruined it for everybody.
1 Nathan Jones
Nathan Jones was so green and unprepared as a wrestler, that he was pulled from his scheduled WrestleMania XIX match, where he was supposed to team with The Undertaker.
Jones fit the Vince McMahon mold of a massive dude with bulging muscles, but like so many others before him (and after him), he just couldn't cut it in the ring or as a character. He left no impact on the wrestling world whatsoever and was just another big body Vince tried to get over.
