Joe Mazzulla is incredibly intense and obsessed with winning, but the Celtics might face some early bumps without Kristaps Porzingis. They might also start the season limiting the minutes of his core players, but does Mazzulla have the discipline to do so if it means a few more losses early in the year? John Karalis of Boston Sports Journal discusses that, why the bench is so important, and the conversation they need to have with Tatum especially to make Joe's life easier.

We continue our look at Celtics camp questions by looking at the defensive side of things. Can the Celtics defense stay at an elite level without Porzingis to start the season? How far can it drop and Boston still be OK? John Karalis of Boston Sports Journal and Tom Westerholm dig into it and look at how the defense might look different, and why the offense might just be good enough for it not to matter a whole lot.

The Celtics hope to repeat as NBA champions this season, but doing so will be even tougher than winning their first championship. Are Jayson Tatum and Jaylen Brown ready to lead a team that just won a championship? How will they handle the trappings of success and try to stay hungry enough to win it all again? John Karalis of Boston Sports Journal and Tom Westerholm discuss how that might look in the locker room, in practice, and in games.
