It is interesting how we react to different statements. I could tell you, with equal levels of confidence, that a .300 hitter is going to bat .200 over the remainder of the season, and a .200 hitter is going to bat .300 the rest of the way. What are the odds that you would act upon either piece of information?
Would you be more likely to trade away your .300 hitter before he tanks, or acquire the .200 hitter in the hopes that he surges?
You know you are not going to trade away your .300 hitter. If he's batted that high for nearly five months, you are not going to risk losing those hits, even if some idiot like me makes an irrefutably strong case for his average to plummet.
