Squawking Baseball: The Best & Worst GMs Of The Aughties

For me, this is a lot of fun, but as a refresher, here's how these rankings are calculated. First, we find each team's expected revenue, based on their third-order winning percentage, and how big their market is. Then, you divide that by what each team's marginal revenue should have been, had they won exactly as many games as their payroll would have predicted. (Draft pick value is also factored in, so the worst teams get slightly more credit than the vanilla mediocre teams.) The end result is PER—Payroll Efficiency Rating—which tells us how well each team spent their payroll dollars.
