After spending his first eight NBA seasons in Charlotte, Walker joined the Celtics via a midsummer trade ahead of the 2019-20 season. He went on to play in 56 games (all starts) for Boston during the pandemic-shortened campaign, clearing 20-plus points per game (20.4) for a fifth consecutive year while making his fourth straight All-Star team. Despite knee issues costing him some time and limiting his minutes throughout the season, Walker matched his career highs in threes per game (3.2) and free-throw percentage (86.4) while rounding out his stat line with 3.9 rebounds and 4.8 assists per contest. He was also 10th in the NBA in charges drawn (0.29) per game. With Jayson Tatum, Jaylen Brown and Gordon Hayward around to share the scoring load, Walker and the Celtics went 48-24 in the regular season before making a deep playoff run. He delivered 30-plus points on 10 occasions, clearing 40 points twice. On Dec. 11, he set his season high with 44 points -- including seven threes -- along with seven assists and two steals against Indiana. A little over a month later, the 29-year-old delivered a 40-point, 11-rebound double-double against Milwaukee. Walker offered much of the same across Boston's 17-game run to the Eastern Conference Finals, averaging 19.6 points, 4.1 rebounds and 5.1 assists. He scored 32 points in the decisive Game 4 of the first round against Philadelphia, then double-doubled with 18 points and 10 assists (a career playoff high) in Game 1 of the second round against Toronto.

As usual, Walker complemented his scoring with strong contributions in assists (5.9 per game, a five-year high), rebounds (4.4 per game, tying his career high) and steals (1.2 per game). In a sign of things to come, he opened the season with a 41-point explosion against the Bucks, ultimately winning Eastern Conference Player of the Week honors for the campaign's opening week. Walker was named Player of the Week a second time in early April after another monstrous three-game stretch. But his biggest game in a season full of big games came Nov. 18 against the Sixers, when the career-long Hornet/Bobcat made 21-of-34 shots en route to a franchise-record 60 points. All told, he scored 30-plus points 28 times, clearing 40 seven times. Walker set a new personal best with nine 3-pointers on Feb. 9 against Atlanta, a 37-point effort. He also racked up 10 double-doubles, falling just short of a triple-double on several occasions. Unsurprisingly, Walker made his third consecutive All-Star game, this time garnering the start at point guard for Team Giannis.

Walker had his best NBA season yet in 2016-17, reaching new heights offensively for the Hornets. He set new personal bests in points per game (23.2, good for 17th in the NBA), field-goal percentage (.444), made-threes per game (3.0, seventh in the league) and three-point percentage (.399). Walker rounded out his line as usual, adding 5.5 assists, 3.9 rebounds and 1.1 steals per contest while shooting 84.7 percent from the free-throw line.

All told, he scored at least 30 points 15 times and collected eight double-doubles. On Dec. 29 against Miami, he became the fourth player in franchise history to reach 7,000 points. All that impressive work got Walker named to his first All-Star Game; he came off the East's bench to tally seven points and six assists. Walker garnered Eastern Conference Player of the Week honors for the week of Mar. 6 thanks to a three-game run in which he averaged 27.7 points, 6.3 assists and 4.3 rebounds.

Walker's fourth season in The Association saw him deliver another campaign of well-rounded productivity. He led the newly-renamed Hornets with 17.3 points per game, adding 5.1 assists and 1.4 steals.

Walker scored 30-plus points four other times. He was named named Player of the Week for Jan. 5-11 after averaging 30.3 points over four games (all wins). Unfortunately, everything changed when he was diagnosed with a torn left meniscus in late January. Walker hurried back from his surgery recovery in early March after an absence of just over six weeks. He played the remainder of the season at less than full strength, averaging 14.3 points per game over the remaining 20 contests (16 starts). Nonetheless, Walker collected two of his four double-doubles after returning to the court.

The point guard averaged 19.5 points and 6.0 assists across four games in the team's first-round loss to Miami, including setting a new franchise record with 29 points on 11-of-15 shooting in the deciding Game 4.
