I do not disagree about Matheny. He was handed a Rolls Royce and treated it like a Model T. If Cardinal management and ownership had hired some one with some ability or competency the Redbirds might have 1 or 2 more championships. So in my view the manager can make a difference. When Bill Veeck owned the St. Louis Browns, he had a day when a group of fans made all the managerial decisions.
See, I don't take the same lesson from that.
In 2011, LaRussa won the WS in 7 games as a result of some pretty wild and unpredictable things happening. Game 6, facing elimination, LaRussa puts Lance Lynn into a tied game, and Lynn gives up back-to-back homers. One strike away from losing the entire series, David Freese, a guy who'd hit 2 triples in his entire MLB career, hits a triple to tie the game. Then LaRussa keeps Motte in for his second inning of work, and he gives up 2 runs to put the Cards back down 9-7, with Descalso, Jay, and Lohse up to bat in the bottom of the inning. Yikes. Somehow the bottom of the Cardinals lineup delivers, sends the game to the 11th inning, where Freese makes history. The thing is, before that moment, Freese completely bailed LaRussa out in a situation where 95% of the time, Cardinals lose, and then the bottom of the order did it again. LaRussa didn't do anything special to win that game. The players won it in spite of some of the decisions he made that didn't work out.
In contrast, the 2013 World Series, we lost because the bats went silent. Our OPS for the series was a pathetic .572. Freese sucked. Matt Adams sucked. Matt Carpenter, who had had what turned out to be the best season of his career, sucked. And then other weird stuff hurt us. Pete Kozma, who's entire purpose as a baseball player is to not mess up on defense, committed 2 errors in one game. Kolten Wong slips and gets picked off to end game 4 (you can argue that Matheney gets the blame for putting Wong in, but does anybody really thing Allen Craig was a better baserunner than Wong? It was the right call). Wacha, who had been absolutely lights out that postseason, gets shellacked in game 6. So other than mess around with the lineup, which probably wouldn't have helped, I'm not sure what Matheney was supposed to do.
I mean, at the end it just comes down to whose players perform, and some luck. If it's close, in a 1 or 2 run game, maybe the manager makes a difference. But in that 2013 World Series, Boston outscored us 27-14. We won 2/4 close games. The difference was the two games Boston ran away with. That's not on Matheney. So while I agree that LaRussa >>> Matheney, I don't actually think that's why Matheney didn't win a World Series, and I don't think having a different manager instead of Matheney necessarily means we would have had more success. If you have specific examples of what LaRussa did in 2011 that Matheney did not do in 2013, or vice versa, that accounts for the different results, I'd be interested to re-evaluate.
