One way or another, it is going to happen.With a 2027 launch date targeted for NBA Europe, the Vegas franchise likely to launch in the 2028-29 season and Seattle soon after, it could be a very lucrative few years for the league.In the case of NBA Europe, the party line is that the vast majority of the competition-wide economics will be reinvested in the continent-hopping league over the first decade.

Its the dividend to end all dividends.As for players and agents, expansion fees fall outside the scope of the existing collective bargaining agreement although they would dearly like to change that.NBPA would love expansion fees to be included in BRISpeaking to the Boston Globe, NBPA Executive Director David Kelly said players are quite interested in NBA Europe because it could serve as another revenue stream for league owners that does not include the players.My issue with NBA Europe is the fact that its outside of [basketball related income], and I think it should be inside of BRI.We look at expansion fees also being outside of BRI is something that, you know, historically has been the case.
