The problem is, if we believe the manager, short-termism is being thrust upon us, regardless of whether it's part of the plan or not.
It's also possible to have a long term vision and framework but get through managers quickly - I'm pretty sure that's what Watford do (and have had some success as well). Their recruitment strategy is gold plated and they generally go for the same "type" of manager, even if they don't hang around when they're under-performing. I'm pretty sure the Watford board could probably name their next 3 managers right now (or at least their top targets). Could be completely wrong but I don't get a sense that we've got the same level of plan at Boro.
