I want a coach, not a scapegoat. I want someone who can gameplan based on who he has and who he is going against. I don't see that from Nolan.
I also had a bigger problem with the fact that Murray didn't make his own hire.
Personally, this doesn't concern me yet. I think Murray made two strategic moves in this hiring:
1) Don't alienate the fanbase by firing Nolan after he arrived back into town on a white horse.
2) If we are gonna re-build, then let him do the work through the rebuild and then take the fall later (i know this speaks to your point about not wanting a scapegoat, but i think there is something there to it).
Nolan is still better than RonRol who had no visible system in play at all. In the end, i'll be concerned if Nolan gets a fair shot at a roster full of talent with a level to compete, fails, and TM still does nothing.
Otherwise, i truly believe that once the pieces are in place, Nolan gets the boot and TM hires his own guy.
