Now is the beginning of a new long game, but let's not forget they were in charge of the Evaluation Years too, with contracts like the Aminu one and a bolted salary sheet. It's not like they were just hired 15 months ago...
Extensions to Isaac and Fultz were also risky and not exactly cheap, considering the injury risk involved.
I haven't suggested to fire them, but I'm not convinced by them either, like I'm not convinced by their choices for the coaching job... Clifford first, too much old style and conservative, and Mosley now... jury is still up, but a few bad signals already, like other members usually point out in the game threads.
