Who do you like?
I kind of like the Celtics a bit. GS has a pretty impressive 19-11 home record which makes me hesitate a bit.
But most of that has been beating up on the weak teams. 13-5 vs u500 teams and 6-6 vs o500. 6-6 vs good teams isn't bad, but looking at who they beat most of those aren't very good road teams, like the Nuggs, Blazers, Bulls, etc. Their best win would have to be vs the Thunder. If you look at teams at a more elite level like the Celtics they lost to all of them 0-4 (Spurs, Lakers, Heat), just 2-7 as a home dog.
Celtics are as rested as they can be. They come in with a 15-9 road record, 11-6 as a road favorite. 5 of those loses came on b2bs. Its an interesting match-up cause everything GS is great at on offensive, Boston is great at on defense.
GS 7th in scoring, Bos #1 in opp. points.
2nd in fastbreak vs 2nd in fastbreak D
8th in ast vs 1st in ast D
8th in fg% vs 3rd fgD
1st in 3 point vs 5th in 3 point D
I think a rested elite defensive team should be able to stifle a decent run and gun (sort of) team.
Last but not least, all 11 of GS home loses 27 out their 29 total loses have been by 5 points or more which covers this game.
