Adding on a few more:
- 2nd ranked at KC, 3528, won Oklahoma as a #1 seed with 2395, who was also at KC.
- 3rd ranked at KC, 935 won Dallas West as a #1 seed.
- 4th ranked at KC, 16, won Dallas East as a #1 seed for their third regional win of the year.
By my count, that's 13 teams from KC that have a ticket to St. Louis, and there's still another week of competitions left.
