The Celtics completed an epic 18-point comeback to defeat the Indiana Pacers 114-111 to take a commanding 3-0 series lead in the Eastern Conference finals.

Boston got clutch performances from Jrue Holiday, Jayson Tatum and Jaylen Brown, while Derrick White made franchise history in the Celtics' Game 3 win.

"No lead is safe in the NBA no more," Tatum told ESPN's Lisa Salters. "(...) You got to believe, right? We always believe we got a chance to win a game."

White became just the third guard in NBA history with four-plus blocks in a conference finals, joining Dwayne Wade and Jim Jackson. The playoff-high in blocks set the Celtics franchise record for guards.

"Close-out games are the hardest," Tatum said. "Been in quite a few of them in my career. Last year, we were down 0-3, and we forced a Game 7, so just never relax. It's not over until it's over."
