Eventually, McIlvaine was dealt to New Jersey in 1999 for Don MacLean and Michael Cage, primarily to open up salary cap room. McIlvaine rounded out his career with the Nets, playing three injury-riddled seasons with the team. In 1999–2000, McIlvaine played 66 games in his best season since leaving Seattle, but injury problems and declining numbers continued to hamper him until his contract was bought out by the Nets after the 2000–01 NBA season. McIlvaine retired with an average of 2.7 points, 3.1 rebounds, and 1.71 blocks in 401 career games.
