Dwane Casey said the Raptors have let go of the defensive principles that guided them at the start of the season.

“We have lost our attention to detail,” Casey said. “I know that’s a nebulous word but being in position where you are supposed to be when the ball is on the floor. Impacting the ball on pick-and-rolls, we have lost that focus in the search of trying to score points.”

The Raptors rank 18th in defensive efficiency at 104 points allowed per 100 possessions. Casey said lack of practice time has had an effect.

“It’s a tight rope,” he said. “You emphasize one thing and you lose the other. Without practice that happens. Defensively we have just lost our edge.”
