Definition: Superstars and absolute go-to guys that fans of other teams coveted. These athletes may not have won national championships, but they left important legacies in their respective sports and are high-profile (if not always supremely successful) pros.
Examples: Roy Williams, Cedric Benson, Lamarcus Aldridge, Cat Osterman (borderline, because...it's softball, mostly)
ESPN Classic Reaction: "I had almost forgotten how good that guy was!"
