We're launching Celtics Weekly in the best way possible - by catching up with legendary play-by-play voice Mike Gorman on his retirement life, and by pulling the best social posts from Celtics Nation with Melisa Valdez. We're also settling the greatest Christmas Day debates, recapping the last week of games against the Chicago Bulls and Orlando Magic, and previewing the upcoming week including today's matchup with the rival Philadelphia 76ers. Join Meghan Ottolini and Marc D'Amico as they catch you up to speed on all things Celtics.
