I also think it's time to admit that IT's sister's death played quite a role in the first two losses.
It's not an excuse that can excuse all of their play, but the way they put their heads down, missed shots, and didn't respond to runs surely had a lot to do with their emotional state. Rondo being out helps, too, but I think most here thought that they'd play much better tonight than they have the first two games after getting some distance from that traumatic experience.
