Definetly have some type of expansion draft where the remaining owners can protect most/some of their players, but some would be exposed to the "new" owners. Have it so the existing owners cant be pinged more than once (either by one or both teams) so the pilaging gets spread around. They should be wedged into the mix for high drafting as well to help along them getting up to speed. Cant outright give them "everything" have to reward those who have been around longer, but have to give them some help.
Knowing how many you keep might help with folks throwing out ideas, previous posted had some good ideas as well!
