"Why does the 538 model love the Celtics so much - check out those title odds!" – Steve

Reminder: Send mailbag questions to mailbag@dailysix.com. I'll try to keep using them as discussion points for conversations in the morning newsletter.

This question actually came in about a week and a half ago, but is worth bringing up since I included the 538 and Basketball-Reference playoff probabilities in yesterday's Week in Review newsletter. It's also relevant because the Celtics are on an absolute tear, and have put themselves in contention for capturing the top seed in the East.
