army navy probably the biggest rivalry of all time bc it extends so far outside of football + whatever local region
if we're talking strictly within the bounds of football its without a doubt ohio st michigan for biggest rivalry of all time but if we talk rivalries of the 21st century i wouldnt even list it in the top 10 bc michigan cant put together a team worth worrying about
scar clemson also not a rivalry at all
ou texas hasnt been a rivalry since vince young left bc texas hasnt mattered since then
penn st vs law enforcement easily the biggest rivalry of the 21st century
