Celtics have the best record in the Eastern Conference since the Trade Deadline. And that's with Fournier not having played much either.
They are certainly still flawed and inconsistent, but it does feel they've found a bit of a groove and really if they can stay healthy, I still think they could be a legit threat in the East (not picking them over PHI/BKN still, but they could at least show some fight in a series). I think some things also depend on how healthy certain teams are come playoff time.
