Boston ran away with the best record in the NBA at 64-18. The Celtics have continued their dominance in the postseason going 15-3. However, that third playoff loss came this past Friday when the Mavericks stayed alive burying the Celtics by 38 points in Dallas.

The Celtics responded from their previous two playoff losses winning by 20 points against the Heat and winning by 13 points against the Cavaliers. Those were road games. Now the Celtics return to Boston properly chastised and embarrassed for their non-show appearance in Game 4 after winning the first three games of the series.

Overconfidence certainly won't strike the Celtics now. Look for Boston to close out the series regardless if Kristaps Porzingis plays or not. The Celtics have won their past five home games, including defeating the Mavericks by 18 and seven points, respectively, in this championship series.

Dallas' role players stepped up in Game 4. That's been the Mavericks' rotation history, though. Their rotation and bench players have performed statistically better at home in the playoffs than away. The Celtics have too much depth and versatility for Luka Doncic and Kyrie Irving to overcome unless they get sufficient help, which hasn't been the case when playing in Boston.

The Mavericks scoring 122 points in Game 4 was an outlier. A case of pouring it on at home long after the Celtics had surrendered. Boston had held the Mavericks to an average of 95.3 points during the first three games of the series.

Joe Mazzulla has grown as a coach. I trust him to make good adjustments and have the Celtics mentally ready and refocused to close out the series in this Game 5.
