A few bugs

I'm guessing there is some sort of minimum filter on playing time to qualify for a certain team. While Jackie Smith played for Dallas, he did not record a single meaningful stat. There are only a few pre-Super Bowl players, primarily it's just Super Bowl Era. He answered the points thing in a different post here. Some positions are weighted differently in terms of their value to the overall team level. So there could be instances where the raw value of the players' values is lower, but the overall team rating would be higher.
