yes it's a bit out of date I think, and not all of the DoF in here do exactly the same kind of thing, it is pretty compelling that pretty much every club that has kicked on in recent years has done so by taking a longer term approach than the average tenure of a manager (about 18 months)
if you leave everything up to the manager they know that in 18 months they'll be in another club most likely, so whey aren't incentiveised to do anything other than a quick fix.
worth noting that none of the DoF on that list are grizzled former managers either.
people were suggesting Warnock as a DoF this time last year ffs
