By the latest calculations, all but four at-large positions in the NCAA field are spoken for. And those four spots are now being contested by only eight teams on Sunday morning.

Here is the projected S-Curve ranking of the "Super Bubble" as of Sunday, March 10 (11:30 a.m. ET):

Last 4 In
Southern Illinois
Tulsa
Boston College
Butler

Last 4 Out
Ball State
Minnesota
Bowling Green
Charlotte

Joe Lunardi will update his Super Bubble one more time Sunday morning, along with his final 65-team bracket projections on ESPN.com, which will be published at 3 p.m. ET Sunday.

Let's break it down, then, using some important (but frequently overlooked) tools:
