The Florida Panthers don’t have the fastest skaters or the most prolific offense. But they have a remarkable ability to infuriate their opponents—and it just won them a championship.

Over the first 29 years of their existence, the Florida Panthers failed to win the Stanley Cup a single time. But they made up for it in years 30 and 31, winning it in back-to-back seasons. It took them six games to beat the Edmonton Oilers in the Final this year — a one-game improvement from their seven-game series against the same team last year.
