Pro Football is a show. Nothing real about it. No different than talented performers in music, theater and dance.
That there is a score is incidental to their performance, not central. When a team gets bad enough to never win, mechanisms come into play to level things out. The point being to keep up the pretense of competition.
It is faked at the highest levels. why not assume it will be at its lowest levels?
I thought only wrestling was fixed.
