You can train what you wont, at the moment, you can't normal score with 20-15 JS JR guards because of high and cheap OD.
Or they will not simple train OD that high because that will raise the salary the most?
If a player with JS 20 / JR 15 and OD 18 had 150k salary
and a player two JS 20 / JR 15 and OD 20 had 250k+ salary would you train it to 20?
This is where we hold them!
