Adding Teams to keeper league

We are replacing 3 owners this year in a 10 team-2 player keeper league.

How should I go about adding them?

Should I create a pool of all the players and let the three new owners select their keepers from this pool? I would draw names out of a hat to determine order of their picking.

Show the owners each roster and let them pick which team they want to take over?

Trading is allowed pre-draft, including picks.

Any advice is greatly appreciated

Have you found replacements already? If you have not, it’s first come first serve to select an existing team to take over.

If you have found the replacements already then harder to assign them an established squad. I would hold a draft and allow them to draft 5-10 players each. Not only keepers but other players that could be part of trades.
