Andrea Pirlo, football's undisputed King of Cool, has officially hung up his boots after three seasons at New York City FC and said last call to a storied career in Italy and for his country's national team. No one has come to embody the notion of "cool" more than Pirlo: from his perfectly disheveled hair that would make Ron Burgundy jealous to the fact that he's not impressed by you, ever, Pirlo commanded your attention and admiration. And what about his insouciant style of play -- one that, to the untrained eye, appeared on the verge of lazy but actually belied one of the game's all-time brilliant minds.
