10. Cam Reddish
Cam Reddish is another player that the Mavericks could consider signing in free agency, and his best basketball could still be ahead of him.
Reddish is entering his fifth NBA season and has played for the Atlanta Hawks, New York Knicks, and Portland Trailblazers. He is only 23 years old and would be a good piece to add to the Mavericks' young core.
Last season, Reddish averaged 9.7 points, 2.2 rebounds, and one steal per game. He played around 25 minutes per game for the Knicks and Trailblazers and started 20 games. He would likely come off the bench in Dallas and provide three-level scoring in defense.
Reddish wasn't known as the best defender at the start of his career but has improved as time goes on. He has the perfect size and length to guard multiple positions and works hard on that end of the floor. Reddish disrupts passing lanes and plays good off-ball defense.
The Mavericks have also been interested in Reddish as recently as last season. Back in January, the Mavericks were reported as a suitor for Reddish via trade, but he ended up being traded to the Trailblazers.
Now the Mavericks can pursue him without giving up any assets as he is a restricted free agent. If the Mavericks can get him for the right price, they should go after him. He brings youth, defense, and scoring.
