Boston Celtics vs Dallas Mavericks preview:
Despite the absence of injured superstar Jayson Tatum, the Celtics (31-18) have been battling for a top-three spot in the Eastern Conference behind Jaylen Brown (on pace for career highs in scoring at 29.4 ppg and assists at 4.9), who recently was named an All-Star starter for the first time in his 10 seasons. There have been conflicting reports about a return this season for Tatum, who has returned to running and practicing after a torn right Achilles in last year’s playoffs.
The Celtics excel in 3-point shooting (ranking second in shots made and attempted from long distance) and defense. Boston’s Derrick White, a 6-4 guard, leads the team in steals (1.3 spg) and blocks (1.4 bpg), ranking seventh in the NBA with 2.71 “stocks” (steals and blocks).
The Mavericks (19-30) are led by Flagg, the No. 1 overall pick in last year’s draft and the youngest player in the NBA. Flagg, who turned 19 on Dec. 21, tops Dallas in total points, rebounds, assists, and steals — the only player in the NBA leading their team in each category this year. The favorite for Rookie of the Year scored a career-high 49 points last Thursday in a loss to Charlotte, setting a record for most points by a teenager in NBA history and most points by a rookie in Dallas history.
Still without injured stars Kyrie Irving (torn ACL) and Anthony Davis (hand), the Mavs have relied on role players such as Naji Marshall (on pace for career highs and scoring and rebounding) and Max Christie (on pace for career highs in 3-pointers, rebounds and assists).
