For example, if you selected '62 Mets, '79 Angels & '01 Mariners and drafted $18-20 million worth of players from those teams, the remaining roster can be filled with any expansion players coming from teams other than Mets, Angels, Mariners.
Or if you went with '62 Angels, '79 Angels and & '01 Angels, the rest of you roster could come from any expansion players except the Angels.
