I'm not for your idea, because I can't imagine who would use it unless the training is quicker than usual single position training. Even for farm teams training for NT's it's not needed as they don't care about playing out of position. But I agree training bigmen at PG to get passing or outside def. training is boring. I personally use such a trainings quite often, but in my eyes there has been still very few teams which has been able to adapt well at present training rules even with changing positions for defence. As a NT manager I can say it's always very difficult to persuade managers for out of position trainings. I would suggest some new training options like every single trainings available on SF, this should be probably acceptable to use for much more teams than using present out of position trainings.
