Celtics vs Mavericks Game 3 Predictions & NBA Picks Today (6/6)

All eyes are on the Celtics to see if they can maintain their momentum in Game 3. A victory tonight would put the C's one away from taking home the Larry O'Brien Trophy, emphasizing the importance of today's game for both sides — especially since an NBA team has never come back from an 0-3 deficit.

The Celtics have dominated the Mavericks to begin this series, holding them to just 93.5 PPG on .445/.265/.651 shooting. splits. It doesn't help that Dallas' attack is essentially a one-man show with Luka Doncic averaging 31.0 points thus far. The second-most successful player on the team? P.J. Washington with a 15.5 PPG clip.

Meanwhile, Boston is averaging 106.0 points while shooting 46.4% from the floor and 32.1% from deep. Not the best success rates but still better than that of Dallas.

Having said that, the Celtics could be without Kristaps Porzingis, who's dealing with a concerning lower-leg problem. The European center played an integral role in Boston's Game 1 victory and even tallied 12 points, four rebounds, and two blocks in Game 2.

Will Kristaps Porzingis suit up in Game 3 of the NBA Finals?

Meanwhile, the Mavericks don't have any injury designations outside of Luka Doncic, who'll probably play through his chest injury.

Dallas is hoping that the home-court advantage pays off tonight. The Mavericks have been solid at American Airlines Center this spring, winning 12 of their last 16 home games — including a 5-3 SU record in the postseason.

Conversely, the Celtics are heading into Game 3 as winners of six straight road games, outscoring those opponents by a plus-5.3 average scoring margin. Additionally, Boston has won back-to-back trips to American Airlines Center, which includes notching a 119-110 victory against Dallas back on Jan. 22, 2024.

Having said that, I expect the Celtics to continue their momentum with a win tonight. I just can't buy into the Mavericks after what happened in Games 1 and 2. The series moving to Dallas won't make a difference, especially with how Boston already succeeded at AAC earlier this season.

The Under on the 213-point total makes sense. The Under is 5-0 in the Celtics' last five games in June and 6-1 in the Mavericks' last seven games against the Eastern Conference. Four of the last five Boston-Dallas matchups also fell short of their projected total with both games in this series finishing with fewer than 213 points.

In other words, expect another solid defensive effort.
