Mavericks +2.5 is my side because Dallas gets an extra recovery day against a Cleveland team returning from Miami.
The Mavericks last played Thursday. Cleveland played Friday and has lost its first 2 games on the second night of a back-to-back this season, by 3 and 12 points.
With Cooper Flagg and Kyrie Irving expected to play, Dallas' bench scoring is the other reason I expect a finish within 2 points.
Mavericks reserves have averaged 42.0 points through 12 games, compared with 31.0 for opposing benches.
