The path to the top is not always linear. For Jill Costanza, it included returning to school and stops in collegiate and military performance before becoming Director of Sport Science and Assistant Strength and Conditioning Coach with the National Football League (NFL) Detroit Lions. Costanza describes today’s sport science landscape as a “Wild West,” where definitions differ by perspective. Her focus centers on assessing the athlete and program effectiveness against the demands of the game to identify holistic interventions. She outlines how intentional systems, a clear communication funnel, and data visualizations help athletes and stakeholders understand the “why,” build buy-in, and tap into competitiveness. Addressing common misconceptions, Costanza clarifies that elite athletes can still have foundational qualities that need rewiring. She emphasizes movement quality, proprioception, and breathing while adapting for individual needs and neurological fatigue.

For Keith Swift, coaching is completely effort based, but it starts with camaraderie and education. As Director of Strength and Conditioning at Wofford College, his philosophy is clear: educate, heal, and enhance. While playing collegiate football and studying exercise science, Swift learned early to question the “why” behind training and encourages his student-athletes to do the same. At an academically rigorous institution, his educational focus fits right in, fostering curiosity, technical precision, and peer coaching. Swift shares how his experiences across professional baseball, the private sector, and collegiate programs each shaped his foundation while making it his own. Amid collegiate challenges — from the National Collegiate Athletic Association (NCAA) transfer portal to the growing authority of student-athletes — Swift holds firm that “there is no substitute for hard work.” His goal is simple: help student-athletes leave with both a degree and a championship ring, setting them up for success in sport and life.
