Besides all the hysteria of yesterday, I do like the way his being in the limelight currently is promoting certain standards of work rate, pride in performance, playing for something bigger than yourself and demonstrating just what you can get back from Everton if you apply/do these things. And, importantly for the players, that you don't have to have grown up in Walton to understand them.
It's completely tragic and actually quite comical that after all the money we've spent since Moshiri came in, we've just sacked our 4th manager in 3 years, were in the bottom 3 in December and were asking Duncan to ride in and save us like it's the 90s again, but hopefully the players have had a glimpse of what's possible on a more regular basis if they show something vaguely resembling the enthusiasm as the interim manager, going forward.
