No, trust your own tactics and theories with your team. It just put the best numbers in the position each position. I would advise watching the game after each season see what you need to upgrade to remain competitive. Even though I can't watch the games anymore only on saturdays since I work 5-9 monday through thursday. I would highly recommend watching the games seeing what tactic is best for your team without gdp and upgrading after each season.
Heading on the right path so far. Are you?
