Wasn't there a study done on the notion of 'protection' a couple of years back, and it was shown to be a myth? (can't remember how it was done--comparing the performance of, say, a #3 hitter when 'protected' by a .300 clean up hitter vs. a .200 clean-up hitter?--no difference). But it's one of those comforting myths we have,, like the virtue of the bunt, 'moving runners up', the 'ideal #2 hitter', and likely most everything we like to discuss!
