This may be the worst free agent acquisition in basketball history as Jim McIlvaine was the man who unintentionally brought about the downfall of professional basketball in Seattle.
After the 7'1" center from Marquette was drafted with the fifth pick of the second round of the 1994 NBA Draft by the Washington Bullets, he never really became the shot-blocking presence he was supposed to become.
Then he kind of "broke out" during his sophomore season by averaging 2.3 points, 2.9 rebounds and 2.1 blocks per game.
The Seattle SuperSonics decided that McIlvaine was a "Shaq stopper" and offered him a seven-year contract worth $33.6 million. Obviously, McIlvaine took the deal.
Both Seattle fans and Shawn Kemp were upset by this because of the latter's ongoing contract feuds with the team. Kemp, who was assuredly a star at the time, wasn't being given the salary increase he wanted and seeing an unproven center get what he thought of as his money didn't help things.
Chemistry issues then killed the team and eventually Kemp was traded for Vin Baker, who would experience an immediate decline thanks to his problems with alcohol.
Meanwhile, McIlvaine never averaged more than 3.8 points or 4.0 rebounds per game.
