Can someone please explain the rule that says the Celtics can't trade for Anthony Davis unless they trade Kyrie?

Both Irving and Davis are on rookie contract extensions under the Rose Rule, allowing them to be signed at 30% of the salary cap. A team can only have one of these on the roster. Kyrie becomes a free agent this summer though, so if the Pelicans are willing to wait to trade they might be able to leverage a big trade package from the Celtics (or anybody who wants to try and match/beat their offer).
