Not sure I can explain it any more clearly, and this does risk getting off-topic, but: Let's say you run Aston Villa, an NBA team. A sound "Moneyball" - ie analytics-based -strategy would be to sell the entire first team (since there is no relegation) and replace them with, why not, the Havant and Waterlooville first 11. This increases your odds of being arbitrarily assigned Ross Barkley, who doesn't have the legal right to play for another side for at least half a decade, and who you are legally entitled to pay around 10% of the market rate. You don't have to scout Gerard Deulofeu, or Seamus Coleman, or Brendan Galloway, and then put in a competitive offer for them - you just try to perform even more ineptly and they'll be assigned to you. You don't have to worry about, say, stadium expenses, because if Birmingham won't pay you, you can move and become Surrey or Shoreditch Villa - or you might just go there anyways because the North under the Tories doesn't make you wealthy enough. There is no shortage of teams who take this approach, and they are praised for using "analytic" or "Moneyball" methods.
Is it so difficult to see why the assumptions behind this approach don't necessarily translate in the rest of the world? Why owners accustomed to this system might make poor decisions elsewhere?
The cognitive dissonance in extolling the "free market" but embracing this model is interesting, but best left for the Ale House.
