Editor's note: This story was originally published on August 18, 2016. With NBA free agency starting soon, we're bringing it back.If this was a list of biggest flops regarding any acquisition, it would be a two-dog race between Lamar Odom and Rajon Rondo.But both of those players came to Dallas in trades.So when it comes to biggest free-agent whiffs, the list is not as jaw-dropping as the one for traded players is.
