4. Boston Celtics
The Boston Celtics did a very nice job of not taking too much of a step back after losing star point guard Kyrie Irving to the Brooklyn Nets. As Kyrie decided that it was best for him to bolt from Boston and link up with superstar forward Kevin Durant and the Nets, the Celtics were left stranded.
It was a good thing that Danny Ainge had an ace up his sleeve with the former Charlotte Hornets All-NBA point guard Kemba Walker. With the way that Kyrie was just not able to mesh with the Celtics locker room and head coach Brad Stevens, this could actually be a positive step to replace him with Kemba.
What the Celtics are still left without is a quality backup point guard option behind Kemba and Marcus Smart. Considering the lack of defensive prowess that Kemba brings to the table, getting Dunn from the Chicago Bulls could be a great move.
The Celtics still have a lot of player and pick capital to make a move on the trade market if Ainge so desires. Even if the Bulls wanted to take a shot on a talented player coming out of high school like rookie shooting guard Romeo Langford to fill other positional needs in the rotation, it could be a popular choice with the fan base.
