Magic numbers for the Regular-season title:
South Carolina: 4 if we want to own the title out-right, 3 if we are fine with sharing it with Mississippi State. Miss State needs to win out, and hope that USC loses 2 of their remaining 5 games of Vanderbilt, LSU, @ Kentucky, @Florida, and Texas A&M to share the title, or that USC loses 3 of the remaining 5 to own it out-right. South Carolina owns the head-to-head over Miss State, but all that gives us is top SECT Seeding.
Kentucky, LSU, Texas A&M, and Arkansas all have 4 losses in SEC play. So they need USC to go at least 1-4 - with the sole win not against either LSU, Kentucky, or TAMU - Miss State to go 1-3, and to win out themselves.
Miss State has the easier path over USC the rest of the way, with only 1 game left against the "top" of the pack, versus Arkansas. USC still has 3 such games, versus LSU, @ UK, and TAMU.....
