Well, I suppose I should assume that with an average number of games missed due to injury - The Celtics will settle in at 56 to 58 wins. They will put more effort in defending the HC winning at least 33 games at home and going out on the road winning 25.
The upside is if the bench really gels and limits the starters minutes to about 30 a night, this team can win in the 60's and compete for HCA throughout.
The downside is if we get injuries upon injuries, we will likely break from the 4 hole as Division champs and get to deal with the Milwaukee - Chicago runnerup in the 1st round and have to deal with Miami, Orlando, and Lakers on the road to get to 18. I don't think that is an advisable trail to get to the 18th title.
I'm thinking 1st paragraph but hoping for the 2nd paragraph.
