Unlike traditional debt, selling a percentage of future earnings can lead to predatory lending lawsuits, as seen with Fernando Tatis. He received $2 million for 10% of future earnings as a teenager, which became a $33 million liability after his mega-contract. This model's high effective cost creates significant legal and reputational risk for funders.

Unrivaled, a women's basketball league, grants players equity, making them co-owners. This model ensures players are motivated to grow the league's brand and engage in marketing, as its success directly translates to their personal financial gain, a stark contrast to traditional salaried player models.

Employee Stock Ownership Plans (ESOPs) are limited in impact. Their structure as retirement accounts prevents immediate wealth creation, and their financial requirements are too stringent for most companies, especially startups, effectively excluding 90% of the economy.

Sue Bird explains how the WNBA's collective bargaining agreement (CBA) historically undervalued superstars. A max salary that didn't scale with the team salary cap meant top players were paid below market rate. She advocated raising the max salary to create a more merit-based system.

Sports franchises defy traditional valuation because they are not investments but 'trophy assets' for billionaires. Their prices are driven by the scarcity of teams relative to the growing number of billionaires who desire ownership, not by financial performance.

Despite America's capitalist ethos, its major sports leagues employ salary caps and a draft system that rewards the worst-performing teams. This centralized, redistributionist model contrasts sharply with the more free-market approach of European sports.

Professional athletes, particularly young ones, should focus entirely on their sport until they secure their second major contract. Only after establishing that financial security should they begin exploring alternative assets like venture capital, a disciplined approach for high-earning individuals with short career spans.

Despite high earning potential, young athletes are often rejected by conventional private banks. Bank regulations require underwriting based on historical balance sheets, which a 21-year-old lacks. This creates a market gap for specialized lenders who can underwrite based on guaranteed future contract value, not past financial history.

A little-known tax change effective around 2027 will prevent public companies from deducting the salaries of their top five highest-paid employees. For sports teams, this creates a huge competitive disadvantage against private teams, providing a powerful catalyst for them to be sold or taken private.
