Celtics werent lucky at all as milk said, the only lucky thing about them was in the offseason being able to get KG and Ray. They were that damn good, there wasnt a lot of luck involved.
As for the OP, whats gonna make or break this team is 2 things that have already been mentioned, Bargs
having a good season and along with that, us not being killed inside when hes i nthe game like what happened in preseason, and how our wing players play. We need Moon to be as good as last year, AP to continue to shoot it well(Jkaps as well), and for one more guy to play a solid 10mpg whether it be Adams or Graham.
Basically the SG/SFs and Bargs
will make or break us IMO
