I think it's the latter. This team has a lot of depth and is a few moves away from being a legit contender imo. We are going to be very good this year. I said this a while back but always have felt this wouldn't be a long process. Ainge has been targetting players for a long time and drafting well.
Our depth chart is very deep right now
pg-Smart, Isiaiah, Rozier
sg-Bradley, Hunter, Young
SF -Turner, Crowder, Jerebko
PF-Sully, Amir, Mickey
C-Zeller, Lee, KO
Pressey, Thornton, Babb all gone or overseas.
I think the Celtics made a concerted effort to draft well and add Lee and Amir. That's 5 guys right there that could and in some cases should contribute heavily this season. Plus the amount of draft picks we have coming up. Ainge is going to make something happen.
