Yas has mentioned that he heard the Panthers are interested in someone who's currently employed by another team but has never been a GM. Who knows how solid his information is, but that could help narrow things down by eliminating former GMs (and, IMO, I think it eliminates DeCosta has he's an "assistant GM" and I think he was a pipe dream anyway).
Which brings up question. I'm pretty sure gm's can not take other jobs til their team is out of the playoffs. IIRC it isn't the same for people under them right?
