This total shouldn't be lower than the Game 2 total. This is a must-win for Boston, but I see the path to victory for the Celtics being on the offensive end. And if the Heat want to take a commanding 3-0 lead, they will need to do it with offense as well.
After combing for 239 points in Game 1 and 216 points in Game 2, I like the over here again.

During the playoffs, Boston is No. 2 in the NBA in offensive rating, and Miami is 3rd. Only Denver is better. On the defensive end, the Heat are 8th, and Celtics are 10th out of the 16 teams who made the playoffs.

The Heat have scored at least 108 points in 9 of their 13 playoff games. The Over is also 10-2 in the Heat's last 12 home games.

Celtics have scored at least 112 points in 12 of their 15 playoff games. The Over is also 10-2 in Celtics' last 12 road games.
