True, it's not absolute like ops. But it can be backed up w/ various observations... Jeter, Bernie and Paul O'Neill were "great clubhouse guys," the Red Sox have a fun clubhouse," etc., etc., etc.... Thus an opinion can be supported to some extent. If you want to give it a value, perhaps 5-10% of winning a title is based on "chemistry." Sometimes talent and luck can override this though. See the 72-74 A's for more.. I think Vance's point is that, in building a team, you can't rely on something as nonquatifiable as "chemistry" to save you. I agree - talent and production are more important. I just don't think chemistry should be completely disregarded as a factor (even if its only 5-10%) just b/c its difficult to quantify by nature. It's a valid point. If you're looking for a template for success, it's the Yankees from 96-2000. Good pitching, hitter, managing and clubhouse. Of course, outspending everyone helped. :)
