Late in the second quarter, with the Boston Celtics up 51-41, Pascal Siakam backed down Jayson Tatum in the post. Siakam got down to just above the restricted area, turned into Tatum, and went up for a layup.
Tatum gave him a slight bump, Siakam missed the bucket, but just as the ball was rolling off the rim, a whistle was blown. And Tatum was not happy.
He immediately walked toward the sideline opposite to the Celtics bench in frustration, clearly angry at the call. Tatum definitely gave Siakam a little bump, but the contact was marginal, and the whistle was clearly late.
