The Celtics will probably miss the playoffs, again. They didn't improve themselves much in the summer. They can make the playoffs because the east is weak, but it's fair to predict them missing out again
I could see both teams with similiar records and battling for the last playoff spot. 40 - 41 wins.
There will probably be some growing pains for the Celtics with all the young players. This team has the potential to be a solid team in a couple of years once the young guys get more experience. Maybe win a division title.
