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. Learn how to build sport science systems, turn insights into action, and keep progressing on your professional path.

The playing field has changed in collegiate athletics, but Kaz Kazadi knows the keys to longevity. Get to know the Texas Christian University (TCU) Assistant Athletic Director of Football Human Performance, renowned for his ability to inspire athletes. Follow his roots from the Democratic Republic of Congo (DR Congo) to playing for the National Football League (NFL) Los Angeles Rams — later becoming a “roaming gladiator” in the Canadian Football League (CFL) and NFL Europe to secure tenure. As a leader in the weight room, strength and conditioning was a natural transition. He recalls choosing a graduate assistantship to embody his “long money” philosophy of purpose-driven education, networking, and positivity. Kazadi compares new Name, Image, and Likeness (NIL) policies to free agency and talent acquisition versus recruiting.
