I know this may instantly seem silly if the idea is to do a Dynasty but I think it would be a good option to have if it isn't on the game?
I'd like to go through a Dynasty and use the proper teams for 2004/2005 so if there's the option to turn trades off this would be good. Once I get through year 1 I'd turn them back on.
Maybe a slider for computer trade frequency would be a good thing to add to 2006 unless someone tells me there already is an option?
