You’ve made a lot of untested assumptions here. Until you can answer these questions, those factoids are meaningless in the context of resourcing:
1. How does the value of an organisation translate to resourcing? Businesses often gain value by reducing their costs, usually by sacking people.
2. Is it possible the high value of these organisations means they in fact are using their resources properly?
3. Given a level playing field, any NFL team is only a one in 32 chance of winning each year, so it’s obvious that some luck is required to win competitions. How much more resourcing would be required to guarantee more than one win every 32 years? The Cowboys are at least sitting on average. Bad luck could account for them not winning a second Super Bowl in that time, which would put them well ahead of the average.
4. In light of the above point, a more granular measure of onfield success tells us more about its relationship to resources. Therefore how does the Cowboys’ win rate compare to its competitors?
