I kinda agree with shoe lover here. Stay in your Div for maybe a season or 2 and get money and all that. I joined last season, didn't expand much, actually won my league championship and now I'm getting killed in D IV... Ive expanded some this season and have 5 G and SF that I train with my big men some older players with decent skills. Im probly getting demoted back to D V and ill just be training and try to earn cash until I get back to D IV then buy some pretty skilled players and hopefully be able to win some games.
Anyway, just don't rush and try to get used to the game this season, find out about training, training minutes, cup and all that, then next season you will have a fresh start and know the game already.
