I'm not thinking about the Celtics/Lakers matchup from last year, and I have no idea why it keeps coming up on the sports channels. The Celtics have been playing so well lately they are a pleasure to watch. They are working on breaking winning streak records. The only threat in the past 3 weeks (from what I've seen) was the near loss to Atlanta (and that day I bet Atlanta +4 - and won).
The Lakers are now like 1-9 ATS, have struggled against teams they should have flattened, and while the win against the Hornets last night was impressive, they're not the Celtics. Except for the Hornets line (+3???), the Lakers have been repeatedly overrated by Vegas.
I really don't understand the +2 lines for Boston. I would expect it to be -2 myself. Maybe some sort of trap but I don't see it.
I expect Boston to win by 6.
