MIAMI — For a night back in Miami, Nuggets guard Bruce Brown was something closer to what he was in college for the Hurricanes than the off-the-bench role player he is for Denver in the NBA. He was a closer, delivering pivotal baskets late with 11 of his 21 points in the fourth quarter of the Nuggets’ 108-95 Game 4 win over the Miami Heat on Friday night at Kaseya Center that sends them back to Denver with a 3-1 series lead and a chance to close out the franchise’s first title Monday. As the Heat clung on to comeback hopes in the final minutes, Brown made a mid-range push shot accompanied with a foul.
