8. Royce O'Neale
Cost to acquire him: One first-round pick and salary filler
Another Brooklyn Nets player whom the Dallas Mavericks have shown interest in is Royce O'Neale, and he may be an easier acquisition for the Mavs due to his lower asking price.
O'Neale is on an expiring contract, meaning that the Mavs shouldn't be too risky in pursuing him, but he would be a great pickup if the front office was confident that they could re-sign him.
This season for the Nets, O'Neale is averaging 7.0 points, 4.6 rebounds, 2.9 rebounds, 0.7 steals, and 0.6 blocks per game while shooting 37.9 percent from the field and 35.8 percent from downtown. He would step in and become Dallas' starting wing, and his 3-and-D ability is phenomenal.
If the Mavs traded for him, O'Neale would become the best defender on the team immediately. His 6-foot-10 wingspan allows him to guard up, and his physicality on the wing is something that the Mavs need badly. A big reason for the Mavs' struggles this season has been their lack of physicality, and bringing in a physical player should be a priority.
O'Neale has played in 44 playoff games in his career, and his 3-point shooting and defense would definitely help Dallas. A trade that nets him and Dorian Finney-Smith would be massive, but the Mavs may not have the assets to make that happen.
