Coaches have relatively little to do with winning and losing compared to the players on the roster.
So, the players on Boston's roster last season were substantially better than the players in Charlotte, Orlando, Brooklyn, Philly, Miami, New York, Indiana, Detroit, Sacramento, Utah, Phoenix, LA, Minnesota and Denver? That doesn't seem to jibe with the general attitude around here toward the team.

The Celtics had really good chemistry, a lot of luck, a good regular season game plan, and a whole bunch of guys playing for their next pay check. They also had quality depth. All of those things helped them win more games than expected. They were also very well coached, which helped too.
Having depth and good chemistry is different than being able to say that the best two or three players on the roster can stand up well next to the best players on the other teams around the league. That's where the Celts fall short, and that's a big part of why they were completely hopeless in the playoffs, where elite players make the biggest difference.
The Celtics won 40 games last season, sure, but if you were to judge their roster based on the collection of talent at the top -- i.e. how good are the best players on the team -- they had one of the least talented rosters in the league. Indeed, they were right there with the Lakers, Timberwolves, Knicks, and Nuggets.
