There are few sports where “leadership” is talked about more than in hockey. The legends surrounding the game’s greats speak to exploits both on and off the ice in which those players buoyed teammates, fans, cities and nations with their words and actions. One caveat here: Although called “Captains: The 30 Greatest Leaders in Hockey History,” Sportsnet magazine did not limit its selections to players who wore the “C” during their careers. It may be subtle and it may go unrecognized beyond the dressing room, but leadership is more than anything that may or may not appear on a hockey sweater.
