Really is a broad and complex discussion this as there are many different variables and perspectives out he same thing so i'll narrow it down a bit to the best examples. Think you are also underplaying massively the quality we have retained and under appreciate how big an opportunity that gives us, while under-estimating the potential downsides if we miss that opportunity and then over estimating our chances of later getting out of that and then building further
Palace - you say were hard to beat. Well after promotion and leaving 7 out of 8 league games and signing 16 players that summer!!!!! Holloway was sacked. Pulis came in only in November which I think you'd forgotten. And this a team you picked as a good example of how to mimic
After we lose Austin, Fer, Sandro you seem to have good faith that we will identify the next Ings,Vardy, Bolasie, Zaha, Lallana, Schneiderling or Ashley Williams and retain them long enough not to get poached by a premier league now even richer or other recently relegated club. What right do we have to , mimic those clubs more so than; Sheffield Wednesday, Blackburn, Bolton, Ipswich, Bradford, Forest, Cardiff, Charlton, Barnsley, Sheffield United? They are all doing the same thing
As for your casino analogy, be interested for you to list their players in our current squad who fit your description of a blind man. Aruably Hoilett, but that was 4 years ago? Many others to make such a strong statement and this still to be relevant and not outdated
