This really shouldn't be so hard, guys.
Turning Craig Biggio, when he was 26, from a catcher into a second baseman man, that was hard. No player in the history of the game had made that move. Not successfully. Maybe not at all.
Turning the young Cal Ripken from a third baseman into a shortstop brother, that took a lot of (Earl Weaver's) guts. There had never been a 6-4, 200-pound shortstop before. Not one, not even for a moment.
