Recent/best highlights of 13-4 upsets

One of the most memorable games in NCAA tournament history was a 13-4 upset.

Valparaiso won in dramatic fashion over Ole Miss in 1998. With 2.5 seconds left in the game with a two-point deficit, the Crusaders had one final shot to tie or win. Inbounding from the opposite baseline, Jamie Sykes threw an inbounds pass to Bill Jenkins at midcourt, who tapped it to Bryce Drew, who tossed up a desperation 23-foot 3-pointer. The shot went down as time expired to send Valpo to the second round. 

And here are some of the most recent 13-4 upsets. First, UC Irvine's win over Kansas State:
