And don't forget the Barkley deal. They waited so long they ended up getting Hornacek, Lang, and Perry in return. This was even worse because they hadn't made much noise in the playoffs since 84'/85' when Moses was still the leader of the team.
At least the roster last year entered the playoffs as the #1 seed in the east. I think it was much more likely going into last season that Simmons would develop a 16' jump shot than the last several months would have unfolded like they have. Nobody could have seen all of this coming. Parts, maybe. But generally you don't see well payed guys on a #1 seed turn completely toxic. If they keep this going until December I'll be surprised if they even have home court advantage in any round of the playoffs. It's addition by subtraction even if they just get picks at this point.
