Do you mean 700k right now or700k if I sell my whole team? Either way you don't really need boatloads of cash of a super group of high salary players to do decently in D.III, check out this team
(23172), he has way lower than yours and a team that looks worse than mine(and worse than many other D.IV teams) but he is 14-0 in D.III and he is still in the cup. You think you know everything about this game but you still have somethings to learn. You are good at the economical side of the game(spending money to make a super team right after the allstar break) but I doubt your skills at the tactical side of the game. That's why I'm confident that with HCA, I'll probably win. That being said, I respect your team and the fact that you've been in D.III.
