Draft

Pick 54 the Celtics select Coleman Hawkins
Explanation: A pick for the future for the Celtics as Carrington provides depth at the guard position. He could be a solid playmaker off the bench in a few years. A potential pick and pop sleeper that can be added on a two way contract is who they target at the end of the second round.
Free Agency

Start of Season
Starting lineup:
White
Holiday
Brown
Tatum
Porzingis
The bench is improved with Harris and Morris joining PP and Horford. Hauser still comes in as an elite shooter. Their 3rd string is full of youth splitting some time in the g-league.
During the season
The Celtics roll on to another 55+ win season. Horford does finally start to look like the old man he is, but still is effective. Harris and Morris both look to be great offseason additions.
