Seriously though, I thought Mordecai had a lot of potential. It's a shame they never really did anything with him.
Me too dude! He just kinda squashed a few guys and disappeared from what I remember, then returned as...
Kevin Thorn...Maybe he should have stuck with Mordecai.
Braden Walker (Chris Harris in TNA) - Famous WWE failure, had a small stint in WWE under the ECW brand where it was obvious he had gained a lot of weight since his TNA days (they were only maybe 6 months earlier). Squashed a few guys and was released after.
Nathan Jones - The guy was a genetic freak, I only really remember him being a part of Team Lesnar at the Survivor Series 2003, had all of the image but none of the skill it seemed.
Tensai - Didn't WWE triple his pay from Japan just to get him Jobbing? Essentially a failed monster heel attempt by WWE, has a pin fall win over Cena to his name but also a loss to 3MB...LOL!
Kaval/Low-Ki/Senshi - Kaval was a contestant on NXT in 2010 maybe? Anyways I think this was his last attempt at a WWE run after he tried under the Low-Ki name back in 2000/2001? Nonetheless it failed spectacularly, I remember him doing the whole old school Cena-style rap disses.
Just a few I can remember from the past decade!
