Performance metrics have become an integral part of sports investing. They allow investors to measure a team's or player's potential success and make informed investment decisions. Metrics like defense rating, win shares, and player efficiency rating can give important insights into a player's value and contribution to the success of a team. Investors can also find inexpensive individuals or teams by using advanced metrics like predicted goals and expected points added. Performance metrics are growing more sophisticated as sports data becomes more widely available, enabling investors to make smarter judgments and maybe generate larger returns. As sports investing continues to evolve, the use of performance metrics is likely to become even more important in identifying investment opportunities.
