Also agree with a lot of that, as flexibility is arguably the most important facet of a relegated team.
To his negative side, yes you can aim to be a Man City light long term but as you point out you cannot assume you have the players after the inevitable player churn of relegation.
To defend him, it really is a difficult problem as until the wheels feel off, you are inevitably raising expectations week on week, but when they do (They have for all of the relegated three clubs at some point) you have to be able to react, either with suitably decent replacements for injuries to critical players (my point above) OR adapt and utilise different players in an alternate way/system (Your point I think, unless I misunderstood)
The choice of approach to such a downturn would depend on what you board level expectations are (where are the players you said were arriving?) and your own level of experience I assume.
Yes we dropped a lot of points in his run in, a lot I put down to my point, a lot down to Leeds arriving at perfect form at the right time, Ipswich doing amazing, and plenty down to your point.
Lots of moving parts but as fans we don’t like what it has meant for us.
