These are the rankings by the selection committee of every team in the field, and is used to determine seeding for the first round. Since there are four regions, just count down each four spots in the ranking to see the seed levels. ......
I just realized one thing from looking at the chart...Akron as a 13 seed should be ranked in the top 52...13x4. Does anyone have time to compare the chart rankings to the actual seedings? Something went wrong from mathematically. 🤔 lol
