Olynyk, who entered the game averaging 8.3 points per game in these playoffs, exploded for 14 of his career playoff-high 26 points in the first 8:34 of the fourth quarter, joining Isaiah Thomas in the offensive charge that gave Boston the 4-3 series win.
Boston advances to the Eastern Conference finals, where it will host the Cleveland Cavaliers in Game 1 on Wednesday. Thomas has had some struggles lately in the playoffs, too, seeing his production dip after his stunning 53-point performance in Game 2 of the conference semis. The Cavs are well-rested and it will be an uphill battle for either the Celtics or the Wizards, without much chance of them moving on.
Olynyk described the series win as a "a team effort".
"This was tougher because it was Game 7", Wall said. "But we kept going and stayed the course".
"We can't have lapses where our defense collapse like that especially in crunch time", Porter said.
That being that on Tuesday night the Celtics very well may receive the top pick in June's NBA Draft.
All 11 games between these teams - all physical affairs - were won by the home team and the Celtics have beaten the Wizards nine straight times at TD Garden dating back to 2014.
But Olynyk believes Boston will have more than a fighting chance of being competitive against the Cavaliers. "I knew it wouldn't be easy at all", Thomas said. Bradley was a member of the 2011-12 Celtics team that lost 4-3 to the James-led Miami Heat, which went on to claim the National Basketball Association title. While it is great that the Celtics have so many options with the lineups they construct, their lack of a real crunchtime final five must make cohesion challenging. He giveth and he taketh away, but he sure does have a habit of pulling out big plays when his club needs them. As long as everybody is busy, as long as everybody feels productive, they feel good about what they're doing and they feel like they're contributing; I think when people have lag time and kind of not enough to do, that leads to getting distracted and complaining or being less productive.
The defeat marked another frustrating end for Washington.
The Wizards had all of the momentum, Bradley Beal was on his way to a 38-point night, and it looked like the C's were on their way to a second-round playoff exit.
John Wall added 18 points and 11 assists for the Wizards, but missed his final 10 shots. "You credit them because they played their tails off".
Olynyk's highlight basket of the night came during the first quarter, when he faked a dribble-hand-off to Thomas on the right wing and turned the corner for a drive to the rack that eventually turned into a three-point play.
Following a Washington time-out with 10:00 minutes to play, they responded with a 7-0 spurt which led to Brad Stevens calling a time-out with 8:49 to play and Boston ahead 94-88.
Olynk paced the Celtics with 26 points with a combination of low-post moves and occasional three-pointers.
All games will tip off at 8:30 and be broadcast on TNT.
Thomas finished with 17 points, six assists, a 3-for-3 mark on 3-point shots and zero turnovers in the second half.
