On the surface Calderwood has a reasonable record in Scotland but once you scratch the surface he really is a total buffoon.
I can't speak for Dunfermline but as alluded to earlier, he totally alienated the youth system at the club.
He also created an awful culture at Aberdeen with the team he put together, guys with a bit of talent but a horrible attitude to the club and the sport. The true level of what shitbags they were was evident when Calderwood (who let them away with murder) left and Mcghee came in and tried to instil a bit of professionalism.
The football itself was an absolute eye sore, hoofed balls long to Lee Miller who would try and win a set piece. That was it.
He won something like 4 of his last 19 games, alienated a lot of fans, pissed off the board, the cup exits to lower league teams (QoTS still hurts )
Dons fans got a lot of stick for wanting a guy out who had brought us so much 'success', especially with the car crash that was Mcghee but I think his career since has seen us vindicated that this guy wasn't fit to take the club forward.
