J-Mac is wagering on the Mavericks to not make the postseason — and no, the play-in doesn't count. Find out why he's fading Dallas in this spot.

The Dallas Mavericks (24-21) will aim for their second consecutive upset victory when they host the Boston Celtics (31-14) on Saturday evening. Dallas is coming off its biggest win of the season, taking down Oklahoma City as an 11.

The Celtics opened as the eight-point favorite with movement on both sides depending where you look, moving Boston either up or down half a point. The C’s are 7-1-1 in their last nine meetings against the Mavs, while Dallas is just 4-10 ATS in its last 14 outings.
