For all the new faces and personnel improvements the Boston Celtics have made, their increased success will be the virtue of individual improvements.
From one to 15, each member of the Celtics must focus on an aspect of their game to improve early on. Training camp will be here before we know it and the time will come for this work to be done.
There is an important role for everyone on the team—from the starters on down to the garbage unit. The key to their season will be improving a singular part of their game individually, so that the team can improve as a group.
If all 15 players improve enough to help the team elevate as a whole, then Boston has a much better chance of advancing deep into the NBA playoffs.
