Because I believe that Wilder does more at the club than a modern "first team coach" does. He's a club manager in the traditional, old-fashioned sense. I think that's what a lot of people are unhappy with, hence the clamour for a modern "first team coach" type appointment.
There's nothing wrong with the modern first team coach model, if you do it properly, but I think we tried to do it last year, 'on the cheap' as it were - I'm not necessarily referring to cost, I think we just skimped on the whole thing, and thought we could replace a traditional old-fashioned type manager role, with a first team coach without taking on board all the 'whole club' things that traditional managers do, and modern first team coaches don't.
I think that's one of the reasons the Selles appointment was such a disaster - he only knew how to be a first team coach, and the club needed more than that, because there was a big void when someone who was a traditional old-fashioned type manager left. This is one of the reasons I think getting rid of Wilder now would be sheer folly - the club isn't set up for it.
I've said it before but the club needs to do proper long-term succession planning for when Wilder leaves, at whatever point that is. Just getting rid of him in knee-jerk fashion without proper planning is likely to be a repeat of the Selles fiasco, which is one of the reasons I'm so against it.
