Hindsight is everything in this question. Personally, I was all for making the playoffs. This was a fun team to get behind after the all-star break. And had they had gotten the 8th seed and played Atlanta, I truly believe we could've gotten at least 2 games in that series, if not push it to 7.
But given that we played the Cavs and got swept, these playoffs were really pretty pointless. And you can't make the whole "growth and experience" argument, because Ainge himself said nobody is untouchable on this team, so growth and experience on a team means nothing if half the team gets traded.
Unfortunately, I have to switch my opinion. Making the playoffs cost us 5-7 spots in this draft, which is HUGE. Could've stayed where we were and took Winslow, could've had a much better opportunity at moving up. It was fun to watch as a viewer, but to make it and not even win a game? At least when New Orleans makes it and doesn't win a game, they still go home knowing Anthony Davis is on their team and at least have a piece to build around. The Celtics don't have that. And making the playoffs cost them the chance at finding a piece of their own
