I will continue to update the Matrix after each round of the sections. This is the February 28 edition. At this point the first category to be completed is the higher seed portion across all four classes. Three of the four were tame upsets within one seed.
Bold indicates the first overall. The last three categories will measure the final number of teams in each class.
