Sports: Mad Marchness!
Let's do the numbers:
East region: 1, 2, 3 and 4 advance.
South region: 1, 2, 3 and 5 advance.
West region: 1, 3, 7 and 12 advance.
Midwest region: 1, 3, 10 and 12 advance.
11 of the 16 were "supposed" to advance and a five seed getting to the round sixteen is as much of an "upset" as a 9 beating an 8.
Duke and GTown going down were clearly shockers. You just don't expect 2 seeds to get bounced. UConn, a 4 seed was defeated because a key player was injured early in their first round game paving the way for an upset. Vandy, the other 4 seed ousted, was in the eyes of many commentators over-rated. Pittsburgh, the other 4 seed that lost, was beated by 5th seeded MSU which at most would be considered a minor upset.
