Welcome to XL Sports Group!

Trusted representation. Intentional relationships.

XL Sports Group is a full-service athlete representation and advisory firm built by experienced professionals across the NFL, NIL, legal, and financial landscape. Our team brings decades of league experience, trusted relationships, and a shared commitment to protecting athletes and their futures.

Every role within XL Sports exists to serve the athlete—providing clarity, advocacy, and guidance through the most important decisions of their careers, on and off the field.

Quality over quantity. Always.

XL Sports Group is intentionally selective. We work with a limited roster of athletes so we can provide focused attention, prioritized advocacy, and hands-on support that goes beyond traditional representation.
