This big retirement wave may have similar effect for some teams like this match, where home team's only adequate keeper was injured:

Overall Navi has been slightly better (more managed) team, their first match ended 1-1. But for Anomaalia keeper was their key player who carried whole team.
Market will be blooded by retirement-risk players and very few potentially good future keepers, the latter for breathtaking prices. All cared u21 teams will have 3 u21 keepers in rotation for hoping big money afte 6-8 seasons. But then most of them who are not ST will be cheap already.
