I'm not keen on a reset button. I do like the idea of being able to move in and 'manage' the franchise in the off season.
Perhaps an option to add compensatory picks to a new owner of an AI controlled team that has salary cap issues - not sure of how it would work, just throwing in it out there.
A PM to all (Franchise owners within the League) sending out one leaguewide message instead of having to copy/paste 31 times.
