Since I haven't found a decent sim to use, I'm going to have to try making one myself... So it will go ahead, but not for a while yet, and only if the sim I produce is half decent.
I know even less about the subtle things of Union than I do Ice hockey, tbh. Also like hockey a lot more
If you haven't had offers, why don't you approach a team? Before play gets under way the squad limitations will be removed, and every team can have as many as they like then, so don't worry if a team doesn't want you 'yet'.
I don't have plans for seconds yet, but I'll look into how many extra players teams have just before the main season gets under way and see if I can work out something so more people get game time.
