Yeah but you answered your own indignation at the question- we did not stay up, we did not sack Rodgers, so your hypothetical outcome is just that hypothetical and worse, unlikely as there is reason to believe it would have happened as you suggest. We did need a way to reset, we were hamstrung by wages, we were stale with a manager who would not walk away and worse we looked like we had become fat and stale as a club. Relegation provided an unpleasant way to address those issues we faced. It’s not ideal, but whilst we have parachute payments, it’s not catastrophic.
I just cannot see why would we sack Rodgers if we had survived, it does not seem especially likely.
