Wasn't quite sure if this would have been deemed as cheating or not (it doesnt as you cant do it anyway) but I was using a 2nd Team as a Farm System to develop players at different positions to make them more versatile e.g. retrain an SS at 2B.
The aim would be then my main team purchase him from auction for full price (avg sale over last 5 sales). Therefore, neither team was benefiting financially. However, I get player who back up multiple positions. Unfortunately, upon trying this, the player in question lost his ability to play 2B once transferred over to main team which makes complete sense to be fair.
Jokes on me that since moving him back (for the same price) he now cant play for 14 days
Just making everyone that the above isnt possible!
