A reasonable New Year’s resolution for the Miami Heat? Aspiring to something more than average. Sunday night in Houston moved Erik Spoelstra’s team in that direction, in a feisty display. With guard Tyler Herro continuing to thrive as both a leading man and a complete contributor and with backup big man Nikola Jovic also filling out the boxscore, the Heat pushed past the Rockets 104-100 at Target Center to make it three victories in their past four games. While 16-14 might not have been the ultimate goal at the New Year’s break, with the Heat 19-13 a year ago at the same break, this had the feeling of somewhat of a statement, in a game punctuated by a scuffle with 35.7 seconds to play that left two players on each side as well as a pair of Rockets coaches ejected. “It’s a shame that that’ll be the discussion of this game,” Spoelstra said in an emotional postgame media session.
