I need to complete my Giambi missions, but he is only eligible at third base, and my third baseman is the best player on my team. I don't want to sub him out for Giambi. Why can't I play Giambi at first base which was his actual position? Am I missing something?
Jason Giambi third base?
Presumably because he didn't become a first basement until ~97 and the bronze is his rookie card, where he'd have been more a 3rd baseman and occasionally outfielder.
