It looks like Jaylen Brown is out from being questionable status hours ago. So I'll go for Heat +1.5.
Heat could use one more win to put some space with the Celtics team for the 6th spot now. They could take advantage of this and play full defense against Tatum and Kemba.
Edit:
Miami Heat tearing Boston at their home-court, a complete change on Miami's game right now, they are hitting three's and playing good defense. Currently up by 26 points.
I had Boston -1.5 so I don't know if they can pull another comeback as Miami is feeling comfortable in this game. Their first 5 is really contributing well in scoring and Jimmy Butler doing his thing with 7 assists already.
