Here's my thoughts on Hurney:
Yes, he can manage the cap.
Yes, he has had some awesome draft picks.
Yes, he loves trading during the draft (which, as a fan, I love, because the Panthers get talked about. Yay!)
Yes, he has had some serious busts.
Is he a great GM? No. Is he a decent GM? Absolutely.
But, at some point, it comes time when a team needs to start fresh. New ideas, new eyes, and new management. It's nothing against him, necessarily, but I do think it is time for a change.
