10British Bulldog
WWE is a PG product these days. This is probably the main reason British Bulldog isn’t part of WWE HOF these days. His problems with illegal substances are well documented, and the company looks to stay away from wrestlers who committed sins in the eyes of WWE crowd.
But his career tells another story, one worth of HOF. Bulldog was Intercontinental, European, and tag team champion back in his heyday. No European wrestler came close to his achievements. Thanks to the fact that his misconduct is now part of ancient past, WWE would do him right if he was part of 2018 HOF Class.
