Average lifespan wasn't hugely different back then if you leave out infant mortality. Infant mortality really skews the averages.
Jefferson lived to 83. Franklin to 84. Madison to 85. Today's lifespans wouldn't have been unfamiliar.
more likely the more popular teams get more interesting records to talk about on TV, Panthers are a small market team so make them 8-8 and other teams get more wins or losses for confirmation bias purposes.
