Baton Rouge, LA (LSU)
Columbia, SC (South Carolina)

Fullerton, CA (Cal State Fullerton)

So, 4 SEC teams are among the de facto top-16 teams. I believe Arkansas was hosed.
5 ACC teams are hosting which I feel is a bit of a stretch.
3-Pac12 teams. 1 Big12 team. 1 Big10 team
LSU and Vandy are obvious Top 8 seeds. I suspect the selection committee will pair up Miss State or South Carolina with the LSU region to eliminate an extra SEC team.
