I have decided that there are going to have assistant GMs along with the main GMs... they will help out, but they cannot make any final decisions on things like trades, signings, cuts, position changes, etc... They hold sway in transactions though, so if you have an assistant you should make sure they think a trade you are making is good... if a GM spot opens up for another team, they get first dibs on it over new members. they cannot go to assistant of a different team however.
if someone wants to be an assisstant, and you are GM, you may choose to accept or reject them... if you reject them you must have a reason. if there are any questions, please ask me
