"again-- i must believe that with all the money at stake for winning in mlb, and all the high priced talent in front offices assigned to evaluate almost every situation, if this was such a logical thing to do, it would be employed on a more regular basis. that is why it is a stupid theory--yes imho, more importantly in the judgement of the proffessionals who run mlb." It hasn't been until recently that baseball front offices have begun hiring statisticians to analyze stuff like this. At the end of the day, they still need to convince a manager to set the lineup and most managers are not brain surgeons - not to mention the backlash if it backfired. It's easier to go with convention than try something radical. I'm not surprised LaRussa (one of the more cerebral managers in the game) tried it first. He has the job security and resume to do whatever he wants. If all people did was go with convention, Knute Rockne wouldn't have revolutionized the forward pass and college football would still look like a rugby scrum.
