help me out here, because I'm curious: if this is true, wouldn't a SABR manager then have a half-dozen very angry bench players because they never ever get to be used? Wouldn't a SABR manager then have a 19- or 20- man roster instead of 25? A SABR manager (and by this, I mean a manager that only manages with advanced metrics) would fail in probably most situations as a manager and wouldn't last very long. Real managers do use stats and even the advanced metrics (I'm sure that Roenicke has looked at them/used them in meetings with coaches and/or players) but they also must stroke the egos of players, unfortunately. There would be a massive revolt by the backup players, some of the guys in the starting lineup would eventually voice their displeasure that their friends aren't getting any playing time, and it could trickle down to the minor league players as well. On topic, I enjoyed the article and saw myself shaking my head in agreement. And there were even a few, "yep, that sounds like 'so-and-so' from Brewerfan.net" comments from my conscience. But it's a necessary evil, having advanced metrics. I enjoy reading about them and learning and improving my baseball knowledge. But it's also not the end-all be-all of arguments. Most of my friends would laugh me right out of the argument if I brought up advanced stats in a normal conversational baseball argument.
