I am brand new to the game, and have some questions...

Unfortunately, I am not great at finding answers on my own haha. I feel like the game should potentially be right up my alley, but I'm finding some things a little frustrating, assumedly because I just don't understand them. After starting a game with a real world mod, I noticed that the draft class players were not the real players. I saw that I could import a draft class from DDSCB21, so I bought that. I can't seem to figure out how to add a real player mod to that game, nor could I seem to figure out how to even import the draft class with the fake players haha. If anyone has information about that or even just how to edit the draft class players in DDSPB21, I would be very, very appreciative.
