Dallas Mavericks vs Portland Trail Blazers Preview & ATS Prediction – 12/29/2025

The Dallas Mavericks will visit the Portland Trail Blazers on Monday night in the final game on the NBA schedule for the night. Dallas enters on a six-game road losing streak and with key availability questions, while Portland rides momentum from a come-from-behind victory Sunday night over a strong Celtics squad. Can the Trail Blazers build on that performance, or will the Mavs get back into the win column? Here, I break down this matchup and bring you my Mavericks vs Trail Blazers prediction.

Key Storylines

Portland snapped a losing streak with a gritty 114-108 win over Boston on Sunday, led by Shaedon Sharpe’s 26 points and a double-double from Deni Avdija. Big man Donovan Clingan asserted himself with 18 points and 18 rebounds in a statement performance. That effort halted a home losing streak and could spark confidence entering Monday’s contest. But the Trail Blazers are on the second game of a back-to-back here and they have to overcome any fatigue to get a second straight win.

Dallas has struggled away from home, dropping their last six road games and demonstrating defensive lapses in a 126-116 loss to Golden State on Christmas Day. Rookie Cooper Flagg has been a bright spot for Dallas with consistent scoring, but health concerns persist for the Mavericks. Anthony Davis is listed as questionable after exiting a recent game with groin spasms and others are dealing with availability issues that have made it hard for the Mavs to realize their full potential.
