Well that's the thing, they had good pitching performances, but were going against superb pitching performances. We had many games those two pitched where they went 6-7 innings and gave up 2-4 runs, and lost 4-3, 3-2, 2-1 against other teams Aces. That's certainly not all on them of course, but Glavine being a contact pitcher was not a benefit in the postseason. Maddux himself had a respectable postseason ERA, but his postseason ERA was much worse that his in season ERA during our postseason stretch (He was a dominating Ace during the regular season, but pitched more like a low end #1 in the postseason). It's certainly not the only reason we only won one WS title, but it's a big contributing cause.
One of my biggest disappointments with JS was his trading strategies in our late 90s and early 2000s years left much to be desired. I fully believe if he had traded for Schilling rather than Ashby back in 2000 we'd have at least one more WS title. JS always doled out or prospects for minor upgrades rather than going for it when we had our players in their primes. Then of course at the end of the run he went 180 degrees in the opposite direction and made all in trades when we didn't have a legit shot.
