Here's a breakdown of Carmel's state championships by class. Remember that from 1980 - 2000, 6A was the largest class. Class 7A and 8A were added in 2001.
MC's totals: 8 in 5A, 2 in 6A, 1 in 7A, and 1 in 8A
All eight of their 5A crowns came when 6A was the largest class.
It's interesting to note that their championships, like those for Montini, Providence, JCA, and Bishop Mac, tended to come in bunches. Never mind the streaks of making the playoffs--we're talking about the streaks of winning it all. Carmel and the others mentioned have won state titles two, three, and four or more times in a row. This is no coincidence. Winning consecutive titles establishes a winning tradition and helps a school recruit. So that's why highly successful schools should be bumped up a class or two. It's like a luxury tax in MLB: sometimes you have to pay to play, and you have to play to win.
