Personnel Evaluation and Roster Construction
The Lions prioritize versatile defenders who can match multiple positions in hybrid schemes. Evaluating size, speed, and football IQ ensures alignment with modern pressures and coverage demands.
Scouting Fundamentals
Film study, combine metrics, and preseason performance feed into a dashboard that weighs consistency, effort, and playmaking ability. Non-contact drills and simulated snap counts reveal how players handle complexity without overcommitting.
