6. William Regal
William Regal is one of those guys that you can call a lifer in pro wrestling. He worked his ass off to make it in American wrestling after coming over from England and as a 24 year old he made it in World Championship Wrestling. Even though he wasn't a WWE or WCW World Champion, he had several runs with midcard titles (IC, Euro & TV), tag titles and a very entertaining run as the WWE commissioner also. His technical matches over the years were his strong suit. He was a very good talker that was underrated in that regard. What Regal does behind the scenes has also paved the way for many stars in WWE like Daniel Bryan. He helped train him when he was getting his start in the business. These days, he helps talent on the road, he helps talent at the Performance Center in Orlando and he's a commentator there as well. Regal's one of those guys that is so smart about wrestling he's always going to have a job as long as he wants to do it. It's very likely that the 45 year old will be a WWE Hall of Famer because he's been in WWE so long, he's been influential to a lot of people there and based on others that have been in the Hall of Fame, he really deserves it. It should be noted that if Regal is ever inducted, they will have to play at least one verse of his "Real Man's Man" theme song because that was classic.
