Higher payroll correlates to more wins in the regular season. Thus more teams with higher payrolls make the postseason than teams with lower payrolls. Thus, more teams with higher payrolls win the WS than teams with lower payrolls. Beyond that, the playoffs are still largely a crapshoot.
At any rate, I'm not looking for the Red Sox to have a payroll in the bottom 50% of teams. I really think they need to reinvest most, if not all, of the money saved from Devers' contract. Just don't sign a superstar to an insane contract.
I am a strong believer that you start with a strong farm and a solid, home-grown core, then fill in the gaps through trades or free agency. Not the other way around.
