When these clubs played in Dallas on Feb. 23, Luka Doncic hit two ridiculous late three-pointers, including the step-back winner with 0.1 seconds remaining. The Celtics players will remember that and want some payback -- and I think they get it now that Jaylen Brown has been cleared to play after missing Monday's loss to New Orleans. I'm pretty sure that Boston trade acquisition Evan Fournier won't go 0-for-10 in this one like he did in his Celtics debut vs. the Pels. The Mavericks are 1-5 ATS in their past six as road dogs.
