As a catalyst for the top statistical defense in basketball this season, Celtics point guard Marcus Smart looks to bring home a major accolade after he was officially nominated as a finalist for Defensive Player of the Year on Sunday.

He is one of three finalists, alongside Phoenix’s Mikal Bridges and Utah’s Rudy Gobert.

Smart is a two-time All-Defensive team member through his tenacity, which has been the calling card of his career. This season, Smart also set a career-high in addition to leading Boston’s defense, which posted a league-best team defensive rating at 106.2. If he wins, Smart would become the first guard to win Defensive Player of the Year since Hall of Famer Gary Payton took home the award in 1996.

The announcement of the finalists came shortly after the Celtics' 115-114 win over the Brooklyn Nets in Game 1 of their Eastern Conference Quarterfinal playoff series. Smart scored 20 points to go with six assists, seven rebounds, and two steals. One of his swipes came off an errant inbound pass by Kyrie Irving, which Smart finished for a bucket en route to the win.

Jayson Tatum came through in the game's biggest moment when the Celtics beat the Nets in Game 1. But the totality of Tatum's performance, and the team's on the clutch final play, exemplified one of the keys to the Celtics' second-half run: unselfishness.

Tatum finished Game 1 with 31 points, including the final two of regulation, when he made a scintillating spin-move around Kyrie Irving before finishing the game-winning layup. But he began the game as a facilitator, dishing out seven of his eight assists in the first half. The unselfishness stood out. But, especially as Kyrie Irving poured on 18 of his 39 points in the fourth to give the Nets a late lead, Tatum had to be the one delivering the victorious blow.

His teammates understood that. Jaylen Brown and Marcus Smart both gave up on shot opportunities of their own on the decisive possession, understanding in the moment that they were better off moving the ball against tight defense. Tatum slipped behind an unsuspecting Kevin Durant to slice toward the hoop, and Smart, facing a double-team, found him in stride for the finish.

The ball movement epitomized the excellent team basketball the Celtics played in their red-hot second half.

"For us, I think that's kind of a microcosm of our season, guys moving the ball, playing unselfish," said head coach Ime Udoka. "Jaylen could've forced a shot on [Goran] Dragic, he saw three guys on him, kicked it to Marcus, he could've forced a shot over two guys flying at him, he pump-faked it, could've took the pull-up, and saw Jayson cutting, so that's where we've really improved at, and it kind of came all together on our last possession."

Five Celtics had at least two assists on the afternoon, and as a team they had 24, compared to 20 for the Nets. Boston's extra level of unselfishness culminated at the game's thrilling conclusion.

Playing Smart

Marcus Smart in another year might've taken an ill-advised three with two defenders in his face. Instead, his unselfishness and intelligence shined on the game's final play, as Smart made the best possible decision at the best possible time.

Smart's growth as a player and teammate has been one of the keys to the team's surge in the second half of the regular season, as he's taken a clear backseat as a scorer to Tatum and Brown. He's played to his strengths as a facilitator and defender, and taken the shot when the time was right.

For Smart, in this game, that time came in a sudden 11-point burst over a three-minute stretch in the third quarter, sparked by his steal of Kyrie Irving's inbound pass and easy dunk. He finished with a box score-stuffing 20 points, six assists, seven rebounds, and two steals, and his all-around game was another microcosm of the Celtics' balanced effort on Sunday.

Size Matters

One game in, it appears the Celtics present a problem to the Nets. Even without center Robert Williams III, their sheer size and length up and down the lineup is proving tough for the Nets to hang with them in the frontcourt.

Al Horford scored 20 points on 8-for-13 (61.5 percent) from the floor, largely from the paint and around the rim. He also pulled down a game-high 15 rebounds; the Nets' five starters had 16 rebounds combined. That included just one for Brooklyn's Bruce Brown, who called out Horford specifically in comments made about the Celtics' defense heading into the game.

It goes beyond Horford. Three Nets starters stood at 6-foot-4 or smaller. Among their entire active roster on Sunday, only Kevin Durant, Andre Drummond, and Nic Claxton stood at 6-foot-10 or bigger. They very nearly overcame those shortcomings, but the size difference showed up in glaring fashion on the final play, when the 6-foot-8 Tatum spun around the 6-foot-2 Irving. This will be something to monitor in the games ahead.
