Are we at the stage where there's a major rebuild needed?

[Eric the Half a Bee]

I think the difference is that 15 or 20 years ago, pretty much every team were haphazard with their appointments, but nowadays we are in a dwindling minority of clubs that don't plan for the longer term, so the effects of it seem more stark.

If you run a business, surely it's standard practice to see what other similar businesses are doing, what they do successfully, what hasn't worked, and copy/tweak to suit. If lots of us fans can suggest what is wrong, how on earth can supposedly top businessmen not see it?
