Nobody knows the real story about the Celtics' management changes. Was Stevens kicked upstairs to change coaches and utilize his guaranteed $30M contract? That's one scenario I've seen in the media. Makes sense, but it could be more than that. Walker, for one, apparently was a problem in the locker room. Maybe Stevens was, too. Maybe other players. You don't know. It does seem as though some players had stopped listening to Brad, which is not a good sign for any coach.
And then there was Stevens' guaranteed $30M contract. And Danny Ainge, who hadn't won a title in 13 years and has had some bad luck with injured FAs--both Hayward and Walker.
But Danny also has made some bad moves the past few years--like not trading Hayward to the Pacers for Turner and McDermott, letting Horford go to the rival Sixers for an extra contract year, and trading Rozier for Walker (Rozier has turned out to be the better player). Seems that Danny forgot about his success formula for the '08 Title by switching to a lower cost rebuild through the draft. He has Smart, Tatum and Brown to show for it in 13 years. A solid young nucleus. But nothing else seems to have worked after Horford and Irving left for free agency. He has failed repeatedly to replace Horford up front with a rim protector. Robert Williams has taken 3-4 years to develop, and he's not durable. Up front height is important for the playoffs.
So maybe Danny decided to retire and play golf. Good decision for him and his health. And now Brad is GM. Is he pulling the strings? If so, he has made a good trade for two bigs and hired a very promising coach. Horford, of course, is a great fit. We'll see how the new coach uses Moses and Robert to develop a solid defensive interior game that's needed.
