So after looking over games notes, official procedure and such, here is what I've deciphered.
We all know ASU, Wofford and GSU each won a share of the SoCon with 6-2 records.
The big point of contention is whether the 4th place teams would be ranked or not. It appears that teams with similar final records will be grouped together (ASU's game notes confirmed this).
Samford is 5-3 and done. UTC and El Cit are 4-3 and have games left against Elon and Furman, respectively.
-If UTC and El Cit wins, then Samford, UTC and El Cit would be tied for fourth. ASU went 2-1, GSU went 2-1 and Wofford went 2-1. ASU, GSU and Wofford all would have defeated the remaining teams, Elon, Furman and Western. Then it would come down to who gave up the least points in SoCon play. GSU gave up 163, Wofford gave up 164 and ASU gave up 238. GSU gets the autobid.
-If UTC wins and El Cit loses, then Samford and UTC would be tied for fourth. ASU went 2-0, GSU went 2-0 and Wofford went 1-1 against those two. Wofford would be eliminated and then it would revert back to head-to-head between ASU and GSU. ASU gets the autobid.
-If UTC and El Cit loses, then Samford would be alone in fourth. ASU won, GSU won and Wofford loss. Wofford would be eliminated and then it would revert back to head-to-head between ASU and GSU. ASU gets the autobid.
So here's what it boils down to.
If Furman beats El Citadel, ASU gets the autobid. If El Citadel beats Furman, GSU gets the autobid.
And before anyone else says, yes the SoCon was vague on this, but this is apparently how it goes.
