Fair enough, but I would put forward the argument that if Coyle had somebody he relied on for advice and guidance, he wouldn't have been stuck in the obvious rut that he was.
Agreed that only one man should pick the team, but all decisions can, and should be, made using all available factors.. When your a one-man-band in thought and deed, there's nobody to steer you on the right road.
Finally, a good manager becomes good by learning from, and studying, other people and past practices. We all bemoaned the fact that the back-room team appeared to be crap for OC, DF is changing that straightaway it would seem. I think we are in for some interesting times.
