The Dallas Mavericks were set on the perimeter with the trio of Jason Kidd, Jim Jackson, and Jamal Mashburn. However, the team lacked a true inside presence, which makes Zydrunas Ilgauskas an obvious choice at number nine.
Though he struggled with injuries early in his career, Ilgauskas turned himself into a consistent presence both offensively and defensively. He was a capable scorer and rebounder, and an underrated rim protector who averaged nearly 2 blocks per game for his career.
Even perimeter based teams need an inside presence to throw the ball to sometimes and Ilgauskas, a 2x All-Star, would have given Dallas a long-term center, as well as an excellent teammate in the locker room.
