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.

Mentorship isn’t flawless — and that’s where its power lies. Erik Hernandez, Associate Director for Sports Performance – Olympic Sports at the University of North Carolina (UNC) at Chapel Hill, has built his career on turning imperfect scenarios into lasting lessons for athletes and young coaches alike. For over 14 years at UNC, he has guided lacrosse, volleyball, and golf, adapting his voice to each culture while holding firm to shared standards of accountability and growth. Hernandez streamlines training into a three-phase model — explosive, strength, and remedial — yet emphasizes that delivery and communication matter more than complexity. He reminds athletes, “modifications are part of progress,” linking health, recovery, and seasonal demands to long-term development. For interns and early-career coaches, his advice is clear: earn mentors by serving others, and learn from every scenario, even the imperfect ones. Hear how mentorship, adaptability, and athlete health point the way forward for stronger teams and longer careers.

What does it take to become an award-winning Director of Strength and Conditioning in the National Football League (NFL)? Justin Lovett reveals the “we over me” mentality that guides his role with the Los Angeles Rams. Lovett reflects on receiving the 2024 NSCA Professional Strength and Conditioning Coach of the Year Award after being an NSCA Member for over 20 years. He draws parallels between working with high school and NFL athletes — where the desired training responses are the same and ability levels vary — making versatility key. Lovett also stresses the importance of finding clean and effective training methods to accommodate wear and tear in football athletes. He compares the Rams’ hiring philosophy to gathering “infinity stones,” emphasizing character attributes, culture alignment, and staff chemistry. Lovett and NSCA Coaching and Sport Science Program Manager Eric McMahon discuss progressing into leadership and the rise of performance director roles, as well as how to seek out career and networking opportunities.
