The Celtics are in a 3-1 series hole after dropping Game 4 on Monday in Madison Square Garden, shellshocked not only by the loss of Tatum but by the reality of facing elimination when the plan was to repeat as champions.

The Celtics’ offense is at its best when all five players are aggressively attacking the rim, spraying the ball out to open shooters and scrambling opposing defenses. It’s hard to do that when one player—Holiday in this case—removes himself from the action.

The St. Louis native went down late in the game with a non-contact injury that had him writing on the ground in pain.
