Well, he sorta did it anyhow. According to New Times reviewer Jose Flores, Mayer instead attempted to please everyone: "Without really keeping or really breaking his promise, he donned a half-a-Heat jersey sewn together with half-a-Cavs jersey." Now confirmed in this photo below, half of his heart is still in Cleveland, but the other half is draped in a black LeBron James Miami jersey. Doubtful that this glad-handing move will inspire American Airlines Arena to play "Heartbreak Warfare" before Heat games this year.
