These aren't your typical Celtics.
After an off-season of roster reconstruction, fans may need a team photo to identify some of the new faces.
Dramatic overhauls typically come with growing pains, so what we expect from the Celtics this year, and what do they expect from themselves?
"I really don't know," said Danny Ainge. "I know that our coaching staff will work really hard, and I believe that we have a good group of players who will play hard, work and develop and play with intensity... but I don't know what to expect, yet."
Gerald Wallace is looking forward to adding a veteran presence and mentoring the younger players.
"I think it's a great experience to come and play for an organization like Boston and be able to play with these young guys and have an opportunity to help them grow and experience a career in the NBA," said Wallace. "I think it's gonna be fun for me."
Keith Bogans isn't buying the "rebuilding" label.
"I think we're gonna be a great defensive team. I think we can harass teams."
And what about the new coach brought in to lead this rebuilding effort? What does first-time NBA coach Brad Stevens expect from a young team?
"I think one of the things that I can take from Butler is we were never expected to do much, and we always took great joy in trying to prove others wrong."
We'll soon find out if the Celtics are able to match Steven's Butler squads in their ability to defy expectations.
