The good news: You did everything right. You didn't bought players for high prices, now you can get them cheaper while having a good infrastructure :)
The balanced news: you forgot the other seats. But these seats are for sucess in the long run. You don't have him right now, so these seats are the better choice than the other one
The bad news: You missed income by building them in one job. But now you have the advantages to other teams.
A better PR would be senseful, in your league I would say level 3.
Can you tell me the cap values please? I know the 500/50 limit for luxury and courtsides. Whats the limit for the other 2 seats?
