The Milwaukee Bucks haven't always been the dominant NBA team lead by Giannis Antetokounmpo and company. For plenty of years, especially in the early 2000s/2010s, the Bucks' roster featured a revolving door of players.
These three Bucks were great, but sadly their excellence was short-lived -- they either flamed out or left the franchise. Milwaukee fans certainly wish that hadn't been the case.
3. Bobby Simmons
Coming off a Most Improved Player Award for his work on the Los Angeles Clippers in 2004-2005, hopes were high for Bobby Simmons when he signed with the Milwaukee Bucks in 2005. His first season was a success, averaging 13.4 points and 4.4 rebounds per game on a Bucks team that improved 10 wins from the year prior. Sadly, Simmons missed the entire 2006-2007 season with an ankle injury. He put up just 7.6 PPG in 2007-2008, and was traded to the New Jersey Nets as part of the Richard Jefferson deal the following offseason.
2. George Thompson
George Thompson joined the Milwaukee Bucks in 1974, following three consecutive All-Star appearances in the ABA. He was a talented slasher at the shooting guard position, holding the ABA's record for most free-throw attempts in a single game with 29. Thompson impressed in his one season in Milwaukee, putting up 10.7 points and 3.1 assists per game on a Kareem Abdul-Jabbar-led Bucks team. That season would be this only in the NBA. He isn't the poster child for one-hit wonders, but given his success in the ABA, fans would've definitely loved to see another couple seasons out of him. He was done after his age-27 campaign.
1. Richard Jefferson
After spending the first seven seasons of his career with the New Jersey Nets, Richard Jefferson was traded to the Milwaukee Bucks prior to the 2008-2009 season. That year Jefferson was a huge piece for Milwaukee, finishing second on the team in scoring with 19.6 points per game. The core of Jefferson, Michael Redd and Andrew Bogut were not given another season to run it back. Jefferson was traded to the San Antonio Spurs after one season in Milwaukee.
