Rust factor, day time start and current form all should factor in this game going Under the total.

Cleveland hasn't played in six days and the Cavaliers weren't challenged defensively by the Raptors then winning, 128-93.. Boston last played on Wednesday.

The Cavaliers have tightened up their defense during the postseason holding foes to 103 points or fewer in seven of their 11 playoff games.

The Celtics are all about defense ranking in the top-three in all the major defensive categories. Boston is giving up an average of 98.5 points during its last eight playoff games.

The Under has cashed in eight of the last 11 meetings between the two teams in Boston.

Matchup-wise, the Celtics have more defensive-minded depth at the wings to throw at LeBron James than last season. The Cavaliers, of course, don't have to worry about Kyrie Irving, who remains out.
