The point is, there is a guy who used to be catcher but can't any more cos he is injured. They want to retrain him to play first base and kick out the guy who is playing first base at the moment even though he is good. I'm asking why - if they are gonna retrain him from scratch anyway - they don't train him for a position which doesn't clash with one of their stars?
that's a good question, rich. and one you should ask the fictional general manager in "Moneyball", because I don't know.
