I understand little of the previous training system, but as I see it, part of the problem was with skills like inside shooting and having to play a guard out of position in a game to train in that area. Inside shooting for a Center is different than inside shooting for a guard--that is not to say guards can't learn post play. For the most part, however, I don't want or need to train my guards to shoot or position themselves like Centers; I want them to be able to make layups when they drive to the basket. That is a different skill set and I should not have to play my guards at the Center or forward position to "train" them to shoot a layup inside. The same holds true for inside defense, although less of a complaint here--good defensive technique doesn't vary as much; however, I want my guards to be able to defend other guards inside not learn to defend a post player; those skills aren't learned by playing out of position in a game in order to become eligible for the skill set--that is pure nonsense; same is true for having to play big men outside to train outside defense; an unnecessary distraction that adds nothing to the game for me.
And except for the economic issues--which are lost on me anyway, I'm befuddled by managers complaining about unexpected improvement by a player on their team. What coach doesn't want to see improvement in all areas by any player? Again, I don't understand the training system as well as most, but if the new system makes the training results more realistic, I'm all for it.
