This might be me just overreacting about the updated list, but this could easily throw a massive monkey wrench into Kyrie Irving staying. Outside of making it to the Finals, it would be a challenge to convince him to stay knowing that youth and Gordon Hayward improving might be the only help he'll get.
Time for Danny Ainge to fully evaluate the team. If he thinks this is a Finals worthy squad, keep going. Otherwise, I'd seriously look into trading Kyrie.
