First off, priate leagues have zero revenue and the minutes do not count towards training. They are a chance to see what your 'A' squad can do in a match.
Gino looks to have a decent build at this point. I am curious if you are always doing one position training or multi. That would be the biggest difference, other than starting attributes. SF's are a real challenge to build but you have done a good job in my opinion. Keep doing what you are doing and then surrond him with some solid talent and you will be back in div II in no time.
Run and Gun is a good tactic but remember not to be to predictable, that is why I won last seasons playoff series.
