I don't really care about Thelwell going, although I don't subscribe to the idea that he was terrible. I think it's exceptionally difficult to tell given the circumstances. I'm also not opposed to having a system that differs from the DoF model either. What I am opposed to is a system that affords too much power to the incumbent manager, no matter who that is. That leads to the sort of issues we've been dealing with for the past few years. There needs to be someone, or some group of people, who are in charge of recruitment with the long term sustainability of the squad as their goal, not acquiescing to the whims of the manager of the day.
Managers come and managers go, when they go we shouldn't be looking at complete rebuilds every time. We've all seen the madness that results from that approach. We should decide what sort of football we want to play and then everything should be geared around that. Recruitment of managers, recruitment of players, age group football, everything, all serving that central mission. In my opinion, it's the only way to have stability and, hopefully, progress at a football club in the modern era. No more flitting from tiki taki to hoofball and back again. That starts above the manager.
