Delusional.
You do know less than 5% of the Knicks' games are played against the Celtics, right? Why do you keep bringing up their season series (which, by the way, was 1-1...and 4-0 in the Celts' favor the year before) as proof that the Knicks will finish ahead?
The Celtics have won the division five years running, including a 2011-12 season where they had the best second-half record in the NBA despite being just as banged up as the Knicks. It's plausible that NY finishes ahead of them, but it shows your truly delusional you are that "Boston isn't one [of the teams] I'm too worried about."
