For training, I just build the type of player I want, bring in a solid supporting cast, then plug up the holes that need to be filled by comparing team stats and ratings. Identifying the best offense to run can be difficult, especially when you don't know your opponent's defensive stats and assignments. I tried Outside Iso for the first time and I did get more production out of Darren for the most part, which is what I wanted. Although I might have to move him to the 2 or 3.
