We don't even know what the "head of sport" does yet, although it seems like it would be the exact same thing Hamlett is doing now, or something very close?
So you admit that we don't know what he will do but also at the same time you think he makes Hamlett redundant and therefore Hamlett should immediately terminated? Do you have a coherent point here or are you just so hellbent on Hamlett getting fired that your immediately gut reaction is to find a way to spin it to justify your motivation?
Getting this team to spend is like pulling teeth. Do you really think they just casually dropped multiple hundreds of thousands per year to hire this guy to do the same thing Hamlett's already doing? Are you even thinking through the implications of what you're saying? Jesus Christ.
Chances are this guy has a more general but powerful role overseeing the club's direction while Hamlett manages more week-to-week activity. If Hamlett wants to promote a guy from USL or trade $100K GAM plus a 2nd-round pick to acquire a player then he probably has the green light to do it. But any serious moves will have to go through this guy.
