Can't get a simple Reverse Relations for Entries field to work

I’m trying to get a simple Reverse Entries working, nothing fancy, but I’m stumped.

I created a little personal project just to help me stretch and learn Craft better. I picked the NFL Draft just because it was an easy dataset (and the draft is fun). This isn’t a live project, just something running in MAMP for learning purposes.

This is the structure:

I have 3 Channels (no singles):

*nflDraft2021 (each draft pick, with Entries fields for the other 2
channels)

*draftClass2021 (the available players)

*nflTeams (the teams selecting)

The nflDraft2021 channel has a Matrix field:

• Matrix Field Handle: draftInfo

• Block handle: SelectionInfo

• Fields in block: two Entries fields: playerSelected and draftedBy (Those relate to the draftClass2021 and nflTeams channels).

What I’m trying to do is on each Team page (the 32 entries in nflTeams channel), have the Related Draft Picks for that team.

I’ve tried to follow along to this tutorial and came up with this attempt:

{% set myEntryQuery = craft.entries()
    .section('nflTeams')
    .all() %}
    
{# title for team page #}   
<h1>{{ entry.title }}</h1>

{# get the related entries from the nflDraft2021 channel #}
{% set players = craft.entries.section('nflDraft2021').relatedTo(entry) %}

{% for player in players %}
  {{ player.title }}
{% endfor %}

I also tried using entry like this post, but still nothing.

I am trying to get the title of the related entry first before attempting to get something from the Matrix field, but that would be my next goal if I can get the first step working.

The team page title shows up but that’s it, the reverse entries don’t do anything, not even an error. So, I’m obviously misunderstanding something but I’m not sure what. Any advice or help appreciated.

{% set nflDraft2021 = craft.entries()
    .section('nflDraft2021')
    .relatedTo({
        targetElement: entry,
        field: 'SelectionInfo.draftedBy',
    })
    .all()
%}

{% set nflDraft2021 = craft.entries.section('nflDraft2021').one() %}
{% set currentTeamPicks = craft.matrixBlocks()
    .owner(nflDraft2021)
    .field('SelectionInfo')
    .draftedBy(entry)
    .all()
%}

{% set currentTeamPlayers = currentTeamPicks|map(pick => pick.playerSelected.one() %}
