#3 Kane
Kane is yet another example of WWE pushing big men, but like his storyline brother, Glenn Jacobs dedicated himself to making this character work, and he did just that. His debut to confront The Undertaker inside Hell in a Cell is still one of the greatest debuts in WWE history and it immediately made him one of the biggest stars in the entire company.
He was never pushed as high as The Undertaker for some reason, but he still made it to the top of the mountain several times, and given his loyalty and resume over the years, he will again be rewarded with this great honour.
He's made several returns over the past couple of years, but given that he was elected Mayor, it's likely his WWE days are numbered, so sending him into the Hall of Fame in 2019 or 2020 would make perfect sense.
