I believe the Celtics are 11-0 leading the first quarter at home. It doesn't matter who they play against.. They go hard in 1st quarter at home. For some reason NBA quarters isn't on my books today, so I don't know the spread for it. I'm thinking since its 3.5 for the whole game, Celtics might be -1/2 or PK for the 1st at -115. Good luck!
