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.. exactly. opinion is a hell of a lot different than empirical evidence. you're certainly entitled to have an opinion that chemistry helps winning. but don't act as though it's fact. opinion & empirical evidence tie together. philosophy & ideology, which is essentially opinion, can be supported w/ empirical evidence. Example of an opinion/ideology ~ social security is good for society. empirical evidence shows that poverty rate went from 30some% in 30's to teens in the 60's. empirical evidence shows people live longer. etc., etc.. Of course, a competing ideology disagrees and shows other evidence such as people don't save as much cause they rely more on govt.. etc. etc.. and you don't have any 'empirical evidence' about chemistry. end of story.
