God Shammgod on emotional Mavericks farewell: ‘Didn’t think this was possible a month ago’



I don't know any other way to interpret this aside from being unhappy with the GM and new ownership.  Shamgod had nothing but great things to say about everyone he worked with in Dallas except no mention of those people specifically.

I thought I read somewhere (maybe Stein) that the Mavs wanted to keep him, but didn't know any details of an offer. And this was a more important assistant job at Orlando than the one he currently holds.
