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.

Tom Williams’ journey to Head of Performance and Sport Science for Major League Soccer (MLS) powerhouse, the Los Angeles (LA) Galaxy, began at a crossroads: pursue traditional coaching or medical pathways. As a soccer “Swiss Army knife,” he embraced early sport science alongside coaching, building a career defined by collaboration and innovation. At the Galaxy, Williams is part of a web of support that uses rich data storytelling tailored to stakeholders and players, guiding decisions and infusing value in every encounter. This system drives their three key pillars: winning championships — including their recent record-breaking sixth MLS Cup — developing a robust academy pipeline, and leading innovation.
