I guess I should have said, "Delta would want each of its regionals to fly both CRJs and ERJs." YX would have CRJs to keep OO and 9E on their toes. 9E would have ERJs to keep OO and YX on their toes. Theoretically, it'd be easier to swap Delta-owned planes among regionals if they all flew both RJs, just in case one of those regionals failed/disapparated/was Comaired.
