Christmas day brings gifts for all the kiddos, but it’s also a gift for NBA fans as we head into the unofficial start of the season. At this point, teams have played about 30 games, or about 35% of their schedule, so we have a decent idea of who most teams are. And since this is a time of year that jolly fat dudes with white beards make lists, I’m legally obligated to share my Celtics and NBA nice and naughty list.
