#4 Kevin Nash
Good lord, another member of The Kliq? If anyone has had numerous bad gimmicks in their careers, it was Kevin Nash. He was one half of a tag-team called The Master Blasters and went by the name Steel. Then, he was repackaged as Oz, a character who apparently got tired of tangling with the likes of Dorothy and decided to pursue his dream of being a pro-wrestler.
Before he was Diesel in the WWE, he was Vinnie Vegas. Yes, the man known was Big Daddy Cool and Big Sexy was now a man who was a 'wise guy' from Vegas. His 'Brooklyn accent' is laughable at best but he still does the promo with ease and is a natural with the camera.
While it's debatable how good an in-ring performer he was, he certainly did know how to do a promo and do it well.
