If anyone's left here... Did a search and couldn't find anything, though I know this has been covered.
Lou Boudreau has some seasons where he has one eligible game at catcher (D/A/B fielding). There are other players like this. Is there a fielding penalty for players that have under 20 eligible games at a position? If so, how steep?
In other words, can I successfully field a team with Lou Boudreau starting 162 games at catcher?
