I don't know if something like this can ever be done, but I'd love to be able to start a "dynasty mode" in a previous season. I've always loved using the create-a-player to create myself and a bunch of friends and place us all on a random team, but I'm getting close to that age where I'm not young enough to be starting a pro career.
By the way, I haven't purchased this game in 8 years so I'm (putting it mildly) a bit behind on things. Could someone tell me a bit about Be A Pro mode and Be a GM mode? Are they any different from a basic "franchise mode?"
