NBA free agency can either be feast or famine for your favorite team. For every net positive signing, think LeBron taking his talents to South Beach and winning championships, there's been at least seven players who have been busts with their new teams. The worst signings far outweigh the players who actually matched the production that their contracts dictated.
By far and away, the team that's best represented on this list or biggest culprits depending on your point of view are the New York Knicks. Since the early 2000s, the Knicks have spent a ridiculous amount of money on players who were less than worthy of a multi-year contract, nevertheless one that handsomely rewarded players who were mediocre at best. This was a common theme under the ownership of Jim Dolan and his former General Manager Isiah Thomas. Jerome James and Eddy Curry are the biggest players to be on this list, both literally and figuratively.
There are other teams that may snicker at the Knicks run of ineptitude playing the free agent market, but they aren't so innocent either.The only stipulation for this list is that players had to switch teams, either by free agency or sign and trade when they were free agents. Players who received extensions from their own team do not qualify for the worst free agent signings since they didn't switch teams. This disqualifies a lot of NBA players who were free agents. Feel free to add players, rank and re-rank who you think the worst free agents to switch teams in the NBA are.
