So far this offseason, there have been a myriad of moves that come across as intelligent and a few that come across as the opposite.
For the Brooklyn Nets, convincing Deron Williams to re-sign was nothing short of brilliant, although history may remember this as the offseason that locked the Nets into mediocrity.
In order to convince Williams to re-sign, GM Billy King executed a trade with the Atlanta Hawks to bring Joe Johnson and the horrible contract that comes with him to Brooklyn. The team also re-signed Gerald Wallace to a four-year, $40 million contract and brought back Brook Lopez with a maximum contract.
Basically, the Nets should be decent next season but will have very little financial flexibility in the coming years. So while the Nets achieved their goal in convincing Williams to return, they aren't exactly bona fide championship contenders either.
Over time, every NBA team makes a mistake at some point. The problem for some teams is that they consistently make bad decisions and aren't competitive because of them.
As you will notice, most of the teams on this list haven't been competing for championships recently, mainly due to the decision making by those in the front office.
