4. William Regal
Largely a case of wrong place, wrong time in my book, but Regal has never held a major world championship. Perhaps if he were in WCW instead of WWF, or WWF instead of WCW, at just the right time, he could have been in the mix. He definitely had the mic skills and in ring ability to contend for any championship out there, and even when he was in the midcard, he was often touted as being one of the most skilled and experienced wrestlers in the world. Winning King of the Ring was nice, but it was no world title. Sadly it doesn't look like Regal will be holding a World Championship in his career, but never say never. He's truly one of the greatest wrestlers of all time, with or without the belt.
