I hear it quite often myself mate, infact the post i quoted inferred it.
Yep i heard it all before and their is reams of stuff on here over the years. In and out and shake it all about. There are some things he did very well, something not some criticism is genuine and some is just kicking the cat and unfair to my mind.
To be frank you weigh it up for yourself, myself - i think many of the criticism of - lack of progress, investment etc aren't justified, 1. because he never promised to be anything then he was - investment wise. 2. As our current situation now proves investments isn't a guarantee of progression as a club - we've had investment now under a different owner and the club as a business has disintegrated and is a basket case, while with investment our league progression from a footballing perspective has seen us face our biggest threat in decades - maybe in our history given the finances involved.
So id surmise, was as era of investment (what all the Bill kickers wanted & much of the accusation you make above) better or worse for Everton than being run sustainably and stability - you know id take sustainably and stability over what we have at the moment. Therefore for all the reasons above, i wouldn't fall into the pitchfork gang.
i realise my opinion isn't the popular group think i know, or conforming with the urban legends, but ill own it.
