if they are JS freaks with barely enough ID and reb, then that is because managers create them that way.
even IF there would be a single position training available for SF, then they STILL would be the least on the national teams.
Guards and inside men can be trained in 1 area, for SF you need to train 2 areas, so the SF will always be weaker in both areas then the other players, and thus being the weakest player on the team.
If someone is training a PF or C, there is no way someone is going to be able to get the Sf the same level of inside training, as he also needs to take care of outside training.
If people wheren't so focussed on trying to improve (or make it easier) the training part, they might have noticed SFs playing at PG (for instance, and I also think playing at C, but didn't test that yet,) DO perform well when the right tactics are chosen. So in fact that already is an improvement in the direction that is being asked here, it just needs to be discovered.
They are not your friends; they dispise you. I am the only one you can count on. Trust me.
