The Raptors will be stressing defense after blowing an 18-point lead in a 128-126 loss to the Timberwolves this past Thursday. They catch Boston minus Jayson Tatum, who will sit out because of a sore wrist.

The Celtics rank in the top-seven in defensive efficiency since big man Robert Williams returned. The Celtics won't be playing fast after a tiring, 121-118, come-from-behind overtime win against the Warriors two days ago.

The Raptors play at a slow pace, too. The Under has cashed seven of the last nine times the Raptors have hosted Boston.
