One day it will all make sense
From what I've read, much of it seems to be focused around the scene where he throws the finals MVP trophy through his office window. Apparently, his office at the forum didn't have any windows, he had very little memorabilia in it (the only reason he had any was because it's expected when you work for a basketball team) and apparently that trophy is the last one he'd have out because it was from a finals they lost.
That's an absolutely ridiculous thing to threaten a lawsuit over.
