De Soto was not the only explorer who was intrigued by Cabeza de Vaca's travels.  Francisco de Coronado was interested in the American southwest based on Cabeza de Vaca's travels.  Before forming an expedition, he sent a friar and a Moroccan to explore the area.  Based on that journey, Coronado would amass a large group of Spaniards and natives to seek treasure.
