Marcus Smart added 20 points and 11 assists for the No. 2-seeded Celtics, who made easy work of what was thought could be a tough series. Boston will wait for the winner of the series between Milwaukee and Chicago. The defending champion Bucks hold a 3-1 lead in that series.
Kevin Durant had 39 points, nine assists, and seven rebounds, breaking free after the Celtics had defended him well in the first three games. But he couldn’t get the Nets the win they needed to extend what instead goes down as a massive failure of a season.
Expected to be an NBA Finals contender, the Nets needed a strong finish just to grab the No. 7 seed.
Seth Curry scored 23 points for the Nets. Kyrie Irving, whose unavailability for home games much of the season because he isn’t vaccinated against the coronavirus contributed to the Nets performing so far below expectations, had 20 points.
The Celtics were under .500 at the midpoint of their season but went 31-10 from there, with Tatum emerging as the scoring star on one of the NBA’s best defensive teams.
That defense limited Durant to just 19-for-52 shooting with 17 turnovers through the first three games and made it tough for him, even as he finally got more shots to drop Monday. He was only 13 of 31 from the field, 3 for 11 behind the arc.
He lost in the first round for the first time since 2010 with Oklahoma City, the first playoff series of his career. He had won nine straight first-round series.
Tatum had 12 points in the third quarter and the Celtics opened a 90-75 lead in the closing seconds of the period. But he went to the bench with a fifth foul with 8:17 remaining and the Nets made a push that got them within three points about three minutes later.
Tatum fouled out with the Celtics leading by six with 2:48 to play. Irving made a 3-pointer and Durant scored to cut it to 109-108 with 1:28 remaining. But after a basket by Brown, Durant could only make one free throw and the Celtics rushed down the floor, with Al Horford putting back Smart’s miss to make it 113-109 with 13 seconds left.
The Nets hoped they could have Ben Simmons make his debut for them in Game 4, but he was ruled out Sunday with more pain in his back that has troubled him since not long after arriving in a midseason trade with Philadelphia.
Tatum didn’t have a basket in the first quarter but got started quickly in the second with two 3-pointers and another jumper. Durant kept the Nets close, and they were down only 45-44 after he found Curry in the corner for a 3-pointer with 3:29 to play. But Grant Williams made three 3-pointers from then until the end of the half, with the final one giving Boston a 58-50 lead.
Celtics: Boston swept its first-round series for the third time in four years. The Celtics beat Indiana in four games in 2019 and Philadelphia in 2020 at Walt Disney World. They lost 4-1 in the first round to the Nets last season. … Williams scored 14 points and Horford had 13.
Nets: Bruce Brown scored just two points after having 26 and 23 in the previous two games, the first time he had consecutive 20-point games in his career. … Nic Claxton scored 13 points. He was 6 for 6 from the field but 1 for 11 at the free throw line, missing his first 10 before making the last one when the Celtics fouled him intentionally.
Coach Steve Nash said he didn’t want to speak for Simmons, but acknowledged there was a mental side beyond the physical problems he is facing. Simmons cited mental health concerns as a reason he sought to leave Philadelphia and didn’t suit up for the 76ers this season.
“I think Ben has addressed that there is a mental component with what he’s going through, but how much and where he’s at with that is not for me to speak about,” Nash said. “But as far as an organization, we’re really pushing to support Ben in any way we can to help him improve physically and get back on the court, and then the mental side of that is part and parcel. They’re not separate, they’re not something that we don’t want to deal with. We want to help if he needs help in any aspect of his life and his game.”
