Osler's Razor

Here are the upsets from the first round of the NCAA men's basketball tournament, from biggest to littlest (based on seeding):

UC-Irvine (a 13 seed) beat Kansas State (a 4 seed)
Oregon (12) beat Wisconsin (5)
Liberty (12) beat Mississippi State (5)
Murray State (12) beat Marquette (5)
Ohio State (11) beat Iowa State (6)
Iowa (10) beat Cincinnati (7)
Minnesota (10) beat Louisville (7)
Florida (10) beat Nevada (7)
Oklahoma (9) beat Ole Miss (8)
Washington (9) beat Utah State (8)
UCF (9) beat VCU (8)
Baylor (9) beat Syracuse (8)

Nine seeds often beat 8s, but this year was a wipeout-- 4 for 4. For some reason, the 12 seeds often beat 5s, and that was true this year as 12s went 3 for 4. 10s also went 3 for 4 against 7s. 

But it wasn't all excitement and tumult-- no 3 seed or higher lost.
