It's been an up-and-down season for the Boston Celtics ... but that's not keeping superfan Mark Wahlberg from staying positive ... saying the Celtics will finish with one of the best records in the East.
Boston was predicted to be one of the top teams in the Eastern Conference ... but currently sit just a couple games above .500 at 13-11.
So, when we saw Mark in NYC promoting his new movie "Patriots Day," we asked about the teams less-than-stellar start.
Mark ain't worried though ... saying it's WAYYY too early to freak out, predicting that the Celts will finish with either the 3rd or 4th seed in the East.
Rest easy, Beantown.
