Yeah, we heard it (a lot) about Pat Burrell and third base, too.
I wasn't taking a shot at you, bkox. I just think the term, and the idea, is silly. Was Pete Rose a "natural" 2B? 3B? 1B?
The thing is, a lot of fans seem to think that because somebody is a "natural" at a given position, they - willy-nilly - should be able to play that position adequately at the major-league level. Frequently, the player can't do that; when the player tries and struggles, that's somehow the player's "fault." Not directing this at you, bkox, but we see it happen, frequently. It's a beast I would prefer not to feed, that's all.
