UC Davis Impact on Washington Coach Chris Petersen I've seen them a few times. Hoosiers is a very accurate account of perhaps the biggest Cinderella basketball story ever.
The high school basketball tournament in Indiana had only one classification when I was in high school which meant that every school, no matter how big or small, were all together in one big tournament. That's how such a small school like Milan ended up beating the big, perennial powerhouse, Muncie Central for the State Championship in 1954. They also beat Indianapolis Crispus Attucks, led by Oscar Robertson, in the semis. Bobby Plump, who hit the shot as time expired to beat Muncie Central, is an Indiana legend.
I'm not sure when the single classification tournament ended but now, like most states, the Indiana high school basketball tournament has several championships based on school size. We'll never see a miraculous run like Milan had in Indiana ever again.
Edit note: Indiana ended the single championship tournament in 1997 amidst much controversy. Many Hoosier basketball fans loved the traditional format because it allowed for the possibilities of Davis vs Goliath upsets. Now only two states have a single tournament format in which everyone competes against each other: Kentucky and Delaware.
