I am not sure Stern is going to look good either way, true or untrue.
He has always handled accusations against the league and refs (as well as player fines and suspensions) with an air of smugness and a vibe of "I'm the commissioner and what I say goes". Even if the allegations are false, he may not do enough to clear the league's name due to him believing that he shouldn't have to defend or justify himself.
I thought admitting the blown Fisher call against the spurs was a step in the right direction (as well as the Crawford suspension), but I'm still not convinced.
As far as Dick, I think that is exactly the type of thing Stern would do IMHO. He had Crawford reffing that Spurs game, right?
