Top Seed Virginia loses To Unknown In Monster Upset

So that is why they call it March Madness.  The Virginia Cavaliers, who many had picked to win the national title were beaten 74-54 by the UMBC Retrievers.  Say what?  I have not heard of them.
The initials stand for University Of Maryland, Baltimore County. 
It was the first time in tournament history that a 16 seed beat a number 1 seed.
It may be the biggest sports upset since Buster Douglas knocked Mike Tyson almost 30 years ago.
