Except for the ones that play 1B, 3B, and RF.
Choo is about to get a huge contract in free agency. And he will probably move to a corner. And he will be fine. And the other guy's point is a valid one....teams all over the league sacrifice offense for better defense up the middle. If Choo returns to Cincy, and they move him to a corner, their team will be improved because they'll play better defense up the middle but will get their offensive production from other places. Your power hitters (and big contract guys) are generally corner infielders and outfielders. Getting that from CF or SS (or even a catcher) isn't as commonplace.
