The main WWE roster is made up of over 70 men and women who all want time in the spotlight. With only so many hours of TV time to go around, it makes it hard to feature everyone.
Some of the superstars on the roster are usually injured, so that frees up some space, but not everyone gets used on the main shows.
Currently WWE has several superstars who have not see the lens of a camera in months or longer, and they are still being paid to just sit on the sidelines.
In this slideshow, we will look at five of WWE's most underused superstars who are in danger of joining Trent Barreta in the unemployment line.
Alex Riley is one of the more unique cases in WWE history.
After he finished NXT, he was paired with Miz during the period where Miz was at his best, and he was given a major boost from the exposure.
Riley ended up tangling with legends like The Rock, Bret Hart, Mick Foley and Stone Cold while working for The Miz, and he probably loved every second of it.
Once he was turned babyface, it seemed like Riley could be the next big thing. He was victorious over Miz in their big showdown, and he looked like he could only go up from there.
That was not the case.
Riley fell further than Brian Baumgartner, and he has only been seen randomly jobbing to other superstars since.
How a talent with that much potential ended up in this position is a mystery.
The Welsh powerhouse and former Gladiator known as Mason Ryan is still employed with WWE.
I know. Shocking, isn't it?
Ryan came into WWE as a member of CM Punk's Nexus, and he filled the role of enforcer. Being the only hand-picked member by Punk seemed to indicate a big future.
After Nexus disbanded, Ryan was on his own, and it did not take long for him to fade away from sight.
Recently, we saw Ryan pop up during a lumberjack match as one of the men outside the ring, although recognizing him was difficult since he had grown his hair out.
Ryan is a massive individual who probably would have been world champion by now if this was the '80s, but since today's wrestler has to be more than just big, he has been all but ignored.
Perhaps they are waiting for the right time to bring him back into the fold, but how long it will take to get to that point remains to be seen.
It might be hard to believe, but it has been over four years since we first met Ezekiel Jackson as Brian Kendrick's bodyguard.
The massively built Jackson was the perfect protector for the smaller-than-average Kendrick, and the two saw a short push before being split up.
Before the brand was shut down, Jackson was a force to be reckoned with in ECW, and he is officially recognized as the final ECW champion under the WWE name.
He later moved to SmackDown, where he would hold the IC title and be a standout member of The Corre.
He tangled with Big Show on several occasions and proved he is one of the most powerful men to ever grace the ring by slamming Big Show as if he did it every day for fun.
After he became the final ECW champion and an IC champion and suffered an injury, we have not seen or heard from Jackson in months.
Jackson is someone who would have been a huge star in the '80s based off his size and power alone, but those days are over, and his limitations have held him back.
Derrick Bateman is one of those people WWE just doesn't seem to know what to do with.
He has been with the company for over six years, and in that time he has been used as everything except a Raw or SmackDown superstar.
Bateman has an interesting look, and his moveset is decent, but WWE has never really invested anything in him outside of NXT.
Whether he is on his way out the door is only known by WWE management, but it would not shock me at all to see him "Future Endeavored" sometime soon.
Quite possibly the biggest waste of a great wrestling talent in the last few years has been Yoshi Tatsu.
Tatsu is an incredibly gifted performer who could have a 5-star match with Daniel Bryan or CM Punk if he was just given the chance.
Rather than use him as a solid performer, WWE has relegated him to random appearances, jobbing to others and being used in YouTube videos.
Tatsu might be one of the next people to see a pink slip, which is sad given how much talent and potential he really has.
If WWE wants to be bigger in the Japanese market, then they would be wise to use Tatsu a little better, but we all know that the cream doesn't always rise to the top in WWE.
