8. Re-signing Markieff Morris to a one-year deal
One decision that the Dallas Mavericks made during free agency that is still extremely puzzling to this day was their decision to re-sign Markieff Morris.
Morris was traded to Dallas as part of the Kyrie Irving deal, but he still hasn't made much of an impact yet. So far this season, Morris is averaging 2.7 points per game while shooting 25 percent from 3-point range and has played in three of Dallas' 19 games. Dallas likely brought him back for veteran leadership, but when you look at who was still available on the market, this move wasn't the best.
There aren't enough minutes to go around for everyone, and if Dallas did sign someone else over Morris they still probably wouldn't play much, but Morris has played poorly this season and seems like a wasted roster spot.
They could have brought in another defensive-minded wing who is younger than Morris or used his roster spot to add a backup big man. This would have given Dallas four centers which doesn't make sense, but things could have gone differently if Dallas knew that Morris wouldn't be in the rotation and would play as poorly as he had.
This shouldn't take away from the fact that Morris is a solid locker room presence, and his teammates seem to love him, but Dallas re-signing him was a move that may confuse fans until the end of the season.
