I don't know if I'd entirely describe this as Luol Deng dunking on LeBron James, as the Miami Heat star was approaching the breaking Deng from behind, making this more of a dunk on LeBron James' hand than LeBron James himself, but you'd certainly be entitled to call it that if you like. James has pulled this chasedown move off so many times that it was jarring to see Deng's throwdown reach the net -- you almost dreaded what was about to happen to him as LeBron approached.
The dunk fired up a United Center crowd and Bulls team that had looked flat early on. Chicago tore out on a 15-6 run right around the time this play happened. With the team facing elimination at home, they're going to need all the plays like this they can get.
