Dynasties or Parity? How MLB, the NFL, and the NBA try to find competitive balance

MLB is heading towards a likely lockout, with missed games in 2027 possible, as owners and players clash over whether to introduce a salary cap. The dispute centres on controlling team payrolls and player pay, while MLB says a cap would make competition fairer; the league also argues that well-run dynasties can be good for baseball.

MLB has proposed a cap of $258.2 million and a spending floor of $180.2 million from 2028, compared with more than $335 million spent by the Mets and Dodgers in 2026 and less than $90 million by the Marlins and Guardians. Players’ union leader Bruce Meyer points to 10 different World Series winners in the past 13 years and successful lower-spending teams as evidence that a cap is unnecessary. The article frames the wider question as whether leagues should favour parity or allow dynasties, noting that NBA Commissioner Adam Silver has said parity may be preferable.
