CHICAGO -- Imagine the National Guard deployed to militarize the perimeter of the basketball court in the expectation of more mayhem. Uniformed police officers with nightsticks are serving as the game's officials. The whole spectacle plays out surrounded by an octagon cage. Apocalypse now: Heat vs. Bulls, second round, 2013 NBA playoffs. If any series invites such dark hyperbole, it's this one. And Game 3 here Friday night did little to change that or tamp out the lit-fuse feel of what's been happening, and what still might.
