Free throws should be trained as a secondary by JS and JR training. It's a logical consequence, there's no real good shooter player that isn't a good FT performer. Just in BB you can find a 16+ JS that can be 3 or less in FT, no sense at all.
I've always thought that stamina and FT should be a percentage of overall training, since it's something every professional player should be doing at some point in training, but think having guys with 1.00 passing having zero career assists and all that also could be improved. On the other hand, I'm not coding this game or writing my own so my opinions will remain just that.
