The famous NHL playoff beard was started by the 1980’s New York Islanders. Apparently, it was started by one specific player, Butch Goring. Since these boys got it going, it quickly caught on, and when the playoffs started, players would avoid shaving their facial hair until they either win the the cup or are eliminated. Some players prefer to start completely clean shaven, while others just keep growing whatever they’ve already got.
*This list will not include Vancouver’s “Towel Power” because although it is a great playoff tradition it isn’t a superstition.
