I can tell you one major thing I've learnt from uni, and that is not to appoint someone who as been in football all their life.
The reason why this is, that the coaches now are being taught by former footballers, and the current mangers coming through have been taught/learnt from former/current managers. This means that a cycle of knowledge from coaches/managers is continuing in football leaving feck all fresh to ever come into this sport.
In saying that if Blackwell ever gets sacked or leaves us we'll probably get another previous footballer to manage us just because he's 'been there and done it before'.
Tis the sad state of football and sport tbh.
