NIL has created opportunity, but it has also introduced confusion, risk, and short-term decision-making. Many athletes are pushed toward deals without understanding compliance, long-term brand impact, or how today’s choices affect tomorrow’s eligibility and leverage.

XL Sports helps athletes grow their brand through meaningful community engagement while aligning with partners that reflect their values and goals. By balancing local impact with high-level opportunities, we help athletes build credibility with fans and position themselves for significant, lasting partnerships.
NIL is new territory for most athletes and families, and strong representation matters.

We manage terms, expectations, and structure so athletes can focus on their sport, knowing opportunities are negotiated fairly and with long-term impact in mind.
