12 Worst free agent signings in Mavericks history

8. Chandler Parsons

The Mavs signed Parsons to a three-year $46 million offer sheet in the summer of 2014. He was 25 years old and fresh off an outstanding season in Houston. Most believed the Rockets would match, but they decided to let the restricted free agent head to Dallas.

Parsons was good friends with Mavericks owner Mark Cuban during his time in Dallas, and he had even more power that general manager Donnie Nelson, according to ESPN’s Tim MacMahon. Letting a 6’9 forward that is still on the roster and in just his fifth season in the league make decisions is wild, but Cuban has never been afraid to think outside the box.

On the court, Parsons played well. He averaged 14.8 points, 4.8 rebounds, and 2.6 assists in 31.4 minutes per game during his two seasons with the Mavs. His availability was spotty, and Parsons missed nine of the team’s ten postseason games. Not being healthy at the most important time of the year hurt the Mavericks' chances of making one final playoff run with Dirk Nowitzki on the roster.

Add in Parsons gaining significant influence over personnel decisions, and signing him may be the worst move in franchise history, but he did produce on the court when healthy. Ultimately, it did not work out for either side, but Parsons signed a max contract with the Grizzlies in 2016 to end his tenure in Dallas.
