Every time the U.S. beats Mexico, which is often, U.S. fans point out how their side is better.
But every time Mexico pulls out results like Sunday's 6-0 win over Paraguay, it's hard to hear U.S. fans' arguments.
The U.S. does well against Mexico and poorly against other top-tier competition in competitive tournaments. Mexico does poorly against the U.S. but holds their own against top-tier competition in competitive tournaments.
So the debate rages on as to which side is better.
My answer: who cares?
