Observations and other notes of interest from Sunday night’s 104-100 victory over the Houston Rockets: – So much of this game said so much about who the Heat are and what they want to be. – When push came to shove, they pushed and shoved. – Showing, just like the victory a few Sundays back against Cleveland, that the fight remains. – But it also showed how difficult it can be at times. – This one as much of a struggle at times as Saturday’s loss in Atlanta. – This time they made shots. – And, so, ballgame. – But as a possible future without Jimmy Butler is considered, this one also showed that there are catalysts elsewhere on the roster. – Tyler Herro continues to fill the boxscore beyond the scoring column. – Nikola Jovic did the same in this one. – And even on an off night by his standards, another double-double for Bam Adebayo. – So now is mixing Butler back in enough? – Because those final seconds showed there is plenty of fight there. – So 16-14 with two days to recover from the road. – With Butler then expected back. – And then a push to something better? – Or was the feistiness in Sunday’s final seconds as festy as it gets? – With Duncan Robinson (foot) out along with Butler, Heat coach Erik Spoelstra opened with a lineup of Herro, Adebayo, Kevin Love, Haywood Highsmith and Terry Rozier. – It was the fifth time the Heat opened with Sunday’s lineup, now 3-2 with that lineup. – The Heat’s sixth lineup of the season. – Spoelstra spoke pregame about Robinson attempting to push through the inflammation in his right foot that flared up in Saturday’s loss in Atlanta. – “I don’t have a timeline,” Spoelstra said, “but he really wanted to try to go today, just didn’t really pass his protocols.
