Ainge deserves approximately 0% of the blame. He did an absolutely masterful job of constructing this team, it's not his fault the chemistry is wet garbage.
I think it's player issue but I agree with you 100%. I posted a thread last month basically indicating no one is to blame. DA brought in talent so how can you blame him? You pick guys that can play and figure it out later. He's done that. Unfortunately, sometimes things don't come together like you hope.
Huh?? Pick guys that can play and figure it out later? So basically running the team on the fly?
Don't you think that is the part of the problem? Isn't part of the front office's job (Ainge, his assistant and the rest of his team) responsible for sitting down and going over which players would mesh well together based on stats, prior success, strengths, weaknesses, etc.
If you're just going to throw a team together and tell them "alright guys, have fun" then no wonder you're going to have the issues we see now.
Isn't that part of analytics and player evaluation?
