5. Not trading Josh Green
Another one of the young pieces that teams were intrigued by from the Dallas Mavericks is Josh Green.
Dallas ended up holding onto Green and not trading him, but could that have been a mistake?
This season, Green is averaging 6.9 points, 2.9 rebounds, 2.4 assists, and 0.9 steals per game while shooting 36.5 percent from downtown. These numbers are clearly a regression from the massive improvement that fans saw last season from Green when he averaged over nine points per game while shooting over 40 percent from downtown.
Dallas could have likely landed a solid piece if they were to trade Green, and he was reportedly one of the players who came up in trade talks with the Atlanta Hawks when Dallas was trying to make a move for Clint Capela.
Dallas refrained from moving Green in this situation, but this shows just how valuable the Hawks thought Green was. This trade would have also forced Dallas to move back in the draft, which could have caused them to miss out on drafting Dereck Lively II, but not moving Green could be something that haunts Dallas for a while depending on the type of trade offers they received.
Green has shown flashes that he can take his game to the next level this season, but putting it all together consistently has been an issue for him.
