I am... Confused.

14 fast trainers, 1 recommended scout, and 600 green packs... this is tanking?

Are you trying to show that teams can still win when they don't have a regular supply of green packs, or attending manager? That would be helpful, to know you can let your team go for a few months with just the daily training, which is what you're saying, right?

For the defensive/offensive/physical part, the players look ok, though there are more evenly balanced than my team. It seems the more positions you expect a player to handle, more even his skills should be. Mine play same position, same formation all the time. I think it might be important to make sure physical is staying up. i have a DC with very high defense, and hope he'll do better next season if I focus on guys physical skills.

Here's my main 11, fwiw
