Observations and other notes of interest from Sunday night’s 123-118 overtime victory over the Dallas Mavericks: – This was the game the Heat couldn’t close out against the Kings at home. – The game they couldn’t close out against the Suns on the road. – This time, the endgame was the Heat’s game. – Closer to what happened in Minnesota. – Which means something. – Because it’s not as if this team has much when it comes to margin for error. – It requires the best of Jimmy Butler. – Check. – Bam Adebayo stepping up. – Such as the late defensive stop on Kyrie Irving and then the 3-pointer. – (We’ll forget the other 3-pointer that hit the side of the backboard). – And a play call from Erik Spoelstra executed to perfection. – In this case, Butler’s basket at the end of regulation. – So a step forward. – And a move to .500. – Needed. – Because it didn’t get easier when Terry Rozier was out with a recurring foot issue. – When Haywood Highsmith left in the second half due to illness. – When Duncan Robinson was called for a foul seemingly at every turn. – The Heat could not have been handed a better break than Luka Doncic being sidelined. – Of course they also were handed ample open shots from point blank. – And ample free throws. – Off. – And clank. – Still, found a way. – With Rozier out again, the Heat again opened with a lineup of Bam Adebayo, Highsmith, Jimmy Butler, Tyler Herro and Robinson. – Of lineup continuity or the lack thereof, Spoelstra said ahead of the game, “I think the most important thing right now is whatever’s working for us, we’ve got to look into that right now.
