These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Bobby spent his whole life taking so much crap from everyone, that it shouldn't be surprising that there's so much built-up rage which helps him play football.
Mama Boucher, who smothered Bobby so much out of pain over her husband and Bobby's father abandoning them. You can see and feel the pain as she mouths the words "And a voodoo woman named Phyllis" from her husband's breakup note.
Coach Klein, who went from brilliant assistant coach to a borderline Cloud Cuckoolander after Red Beaulieu stole the playbook he spent years making, so he could become head coach rather than Klein.
