OPS is a good stat to use to evaluate players. It is not the be all end all stat. Some people seem to think that if you follow OPS, you only follow OPS and only like walks. In the 60s and 70s, players were judged on their BA, now it's moved to OPS. I won't say that the guy with a .787 (Counsell) is better than the guy with a .778 (Hart), I'll call it pretty even with the one slightly ahead right now. If the difference was .787 (Counsell) vs .608 (Hall), I will easily say one is better than the other. I take my girl to the park all the time. She only knows about the Brewers, she doesn't know any of the opposing players. But she can look at OPS and tell generally how good the player has been playing. Between a race car driver and a person with a masters in structural engineering, I'll assume the engineer is right when we're talking about what features to have in a car to survive a car crash. I don't care how many more hours the driver has spent in a car, one has specialty knowledge that the other doesn't.
