I largely agree with what you have included above Rodders...I'd add that KEA was serviceable for the club in his time, def not poor.
I think the overlying theme though, as many have mentioned, is that the budget he has been given each year essentially had to completely rebuild a squad. And to add to that, you can see for the most part in his signings, there is a definite correlation between money spent and quality of the player, Westwood excluded imo. And if the case happens that one of these players flops, there is a very good chance their weekly wage is something that will not kill us...it's not like we have Habib Beye sitting on our bench collecting 50k each week. This yet again points to one person, and while I am not a rampant Lerner basher, he has to take blame here for the lack of quality the squad possesses.
