Scott Ostler of the San Francisco Chronicle on the Giants trade for Freddy Sanchez:

Unless he has suddenly lost it at age 31, he will stabilize a shaky position and add professional hitting . . . A preliminary background check on Sanchez turned up no evidence that he'll be anything but a stellar addition to the Giants' clubhouse . . . The Giants are a team with excellent chemistry, according to most amateur baseball chemists. If they don't make a legitimate charge now, the concept of baseball chemistry will be forever rendered a joke.

Professional hitter! Great clubhouse guy! Chemistry!

I won't deny that Sanchez will be useful for the Giants, but when you see those words written in connection with a trade, the person doing the writing is on the side that lost the trade.
