Don’t use the option association if you want database data. association will also include transactional data, which is a totally different story!
What is your exact question. On the page, it looks like you have two entities Team and Player and they have an association Player_Team. You seem to be correctly retrieving the data on the page, so what’s the issue?
You need to choose datasource as “Association” and then in the entity path click on Player_Team and it will show Player beneath that. Select the entity Player from there.
