I'll give you that soccer's low barrier to entry is a genuine strength, and the way it offers opportunity to kids in poor communities matters. That's a social good, not proof of sporting greatness. By that logic, running or tag would be the greatest sport on earth. Enjoyment isn't cold, but it's also not a reliable test, because people enjoy what's familiar. The real problem stands: soccer rewards chance too often. Basketball and tennis crown the better side far more consistently. A sport where a deflection can undo ninety minutes of excellence isn't the greatest, just the most widespread.
