NBA playoffs: Celtics force Game 7 with Derrick White buzzer-beater, on verge of historic comeback vs. Heat

Hug your closest Miami Heat fan. The Boston Celtics have forced a Game 7, and in dramatic fashion.

After previously falling behind 3-0 in the Eastern Conference finals, the Celtics defeated the Heat 104-103 in Game 6 on Saturday to send the series to a winner-take-all showdown in Boston on Monday to decide who will play the Denver Nuggets in the NBA Finals.

Game 7 is scheduled for 8:30 p.m. on TNT.

The Celtics have made history just by forcing a Game 7, joining the 2003 Portland Trail Blazers, 1994 Denver Nuggets and 1951 New York Knicks in evening a series after being down 3-0. Now they get to find out if they're the first team in that group to win.

Derrick White the hero for Celtics

The Heat might be in the middle of a collapse, but the game nearly ended with a Boston collapse. The Celtics led by as much as 10 points midway through the fourth quarter, then coughed up the lead.

The Heat's final points came on an unreal turn of events, when the Celtics challenged an Al Horford foul on Jimmy Butler while up two points. Instead of getting rid of the foul, it gave three free throws instead of two for Butler, who made them all.

The Celtics got the ball back and saw Marcus Smart attempt a game-winning 3-pointer, which missed. Derrick White got the rebound, though, and won the game.

It didn't look like White got it off in time, but replay confirmed him as the hero.

It was still an ugly win for the Celtics

The Celtics got the win by once again looking like a top-tier team facing a play-in team for most of the game. Unlike the previous two games, though, they didn't do it by shooting lights out from 3-point range. Instead, it was a suffocating effort on defense anchored by center Robert Williams, or at least a putrid night for Miami.

Jimmy Butler and Bam Adebayo, once the dominant forces in this series, looked like a shell of themselves for the most of the game. They entered the fourth quarter shooting 5-of-29 from the field. As a team overall, the Heat finished the game shooting 13-of-34 in the paint.

Meanwhile, the Celtics struggled shooting from deep, finishing 7-of-35 at the perimeter, but made up for it with a pair of strong nights from Jayson Tatum and Jaylen Brown. The Heat defense struggled to stay in front of both of them all night, and the pair combined for 57 points.

The whole game really should have been more of a blowout, especially when the Celtics built up a 13-point lead in the third quarter. What kept Miami in the game was their previously unheralded group of Gabe Vincent, Max Strus, Caleb Martin and Duncan Robinson.

The Heat kept pushing late in the third quarter and early in the fourth quarter, at one point taking the lead on a rare basket inside from Butler.

It didn't last. Brown scored on the next possession to take back control for the Celtics. Three minutes later, they were up by 10 again. And then the Heat came back, again. Had it not been for a pair of missed Robinson 3-pointers in the final minutes, we would be talking about a very different game.

But he did, so the game ended with the Heat looking older than the Celtics. They looked less talented. They looked like they were grinding. Which they were. It just no longer looked like the path to victory it did when they were making all the shots and hustle plays in the first three games.

And now, they need a win on Monday lest they join the 2004 New York Yankees in blowing a 3-0 lead to Boston.
