I'm not going to go as far as rluzinski and say that Yost has no impact on the clubhouse. Ozzie Guillen's clubhouse is certainly going to have a different vibe about it and his players are held to different expectations. Also, when Willie Randolph was fired, I remember reading comments from Mets players that Manuel brought with him a much more relaxed attitude, which seemed to rub off differently on the clubhouse. So, it seems to me like managers can affect the clubhouse--obviously the Brewers clubhouse would be different if Yost called out players and benched them after they made mistakes, as some here suggest he should. However, what impact does any of that have on the field? Is there any evidence of a certain team personality being more conductive to winning? I don't think it makes much of a difference at all. The Mets brought in a new manager, but it doesn't get rid of any of their flaws. If the Brewers got rid of Yost and company, the players wouldn't magically "learn" how to hit with RISP or not swing at breaking balls in the dirt. These guys have all been playing baseball since they were 5. They are paid professionals. I'm not saying that coaching has no impact at all, if it did, what would be the point of all the work they did in spring training on baserunning and defense? I'm sure that made a difference. However, what we're trying to say here is that there is no way to statistically prove that Yost an company's attitude/demeanor/coaching styles/personalities have any impact whatsoever on the players' performances. The Brewers have "learned" to win on the road this year, but there are so many factors that go into that success that there is absolutely no possible way to pinpoint it. You don't have to write a novel to realize that. Maybe it's because their defense is better--but how much of that is because of Yost's staff and how much of that is just because we brought in players that play better defense? Most players are going to follow the same curves--they get better as the years go on until their bodies catch up with them. Unfortunately, there is no way to credit the coaches with any of that.
