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.

Football is evolving fast, and the coaches who keep pace are the ones who control what they can and win the little details. Ted Rath, Director of Sports Performance for the New Orleans Saints, reflects on over 15 years in the National Football League (NFL). He explains how training times, availability, and sheer athleticism have shifted with the game's expansion. Rath makes the case for gaining a well-rounded experience by coaching different sports, seeking knowledge, and being patient on your path. He also shares his linear progression approach to sport science that keeps new tools actionable and avoids technology overload.
