Here's a randomly filled in NCAA Men's Basketball Tournament bracket. If you don't like this one, press reload for another. It's currently set to use the initial pairings for the 2019 tournament. Each game is chosen randomly as follows: if the two teams involved are seeded 'x' and 'y', then Pupset = min(x,y) / (x+y). (See note.) (Pick Kansas, please.)
