one time i have to agree with you trainerman.
Its completely unrealistic and it leads to funky unrealistic lineups and kills competition.
and it takes the fun out of training, especially for newcomers it must be weird.
but if you take f.e. the 40% and increase reb instead, or for OD training increase ID or sth. then it could be that we ONLY train OD and PA for a few seasons and have a complete player in the end because of the increased crosstraining effect.
however i think it is a nice idea.
train 100% at the original postion and reduce it (-10%) at all other positions. that 10% of the training will be added to the cross training effect.
