How to make a sub collection of a public REST API a data recource

How do you make a sub collection of a public REST API collection a data resource? For example:

https://site.api.espn.com/apis/site/v2/sports/football/nfl/teams
Get Collection Method
Config:
Response Key Path:
sports

I would like to set the data resource to REST API get collection nested array leagues[Teams][Team]

I’m having a terrible time understanding the best way to do this.
