Last season, the Dallas Mavericks had the 16th-best 3-point shooting percentage in the league. They converted 36.4 percent of their long-range attempts. Kyrie Irving, Dante Exum, and Brandon Williams were the team's leading 3-point shooters, as they each made above 40 percent of their attempts.
So, it's clear this is an area the Mavs need to improve in, especially considering how poorly they ended the year from downtown. Dallas will also need other players, such as Klay Thompson and P.J. Washington, to help improve their shooting. Cooper Flagg could help the Mavs in this area, but Dallas must be patient with his shooting, as the rookie's shooting wasn't great at NBA Summer League.
