Perhaps I give KP less credit than they deserve, but my interpretation of history (based on no inside knowledge), is that they hit the absolute jackpot hiring Nigel Pearson whilst still being so green that he could run the football side of the club in the same way that Ferguson ran Man United (which admittedly, doesn't exist in 2024).
As a result of that, NP brought in Steve Walsh to the club to lead player recruitment, who in turn, set up a world class scouting methodology based on data.
Meanwhile, Nigel and Shakey knew that the club required a proper sports science approach that hadn't really been applied, even in some Top clubs (apparently Jose ripped what sport science there was out of Man United during his tenure).
Finally, Nigel had immense man management skills - developing players like Marhez, Drinkwater and Vardy that left to any other manager, would most likely not have flourished. This also built the best team spirit the club has ever had (at least when it hasn't revolved around drinking culture).
All of this was allowed to happen because we didn't have a DoF and through luck or judgement, gave NP the freedom to build an elite set up at a mid table championship team.
For my money, this laid the foundations for everything good that has happened over the past decade and which KP and Rudkin have tried to take the majority of the credit. It's also why in my opinion, past performance is not an indication of the future, because Rudkin now has a vice like grip on his position and the freedom to develop the club and what footballing structure we had has been dismantled since 2016 (as we saw when Steve Walsh decided to leave and we bought in duffers like Silmani and Musa!).
*I will say that in this interpretation, I have to give credit to KP for the financial backing and space given to NP and others to build that foundation.
