Besides the transfer list, changing your team name and etc. I don't think there's any way the players on your team can develop their skills in the off season. It happens in the "A" players go to MJ, Hakeem, Pat Ewing to reshape their skills and become better for the next season it would be cool to actually have something for your players to do wouldn't you think so ??? Instead of buying or selling during the off season week . take the off season as a sign of improvement inside your team before looking to get that star from another.
While the champions get promoted , what about the demotions and teams that have to be in that same league for another year ???
