As promised...
There are eight scenarios left:
Minn-Det-Minn: JG wins
Minn-Det-Det: JG wins
Minn-Ind-Minn: JG wins
Minn-Ind-Ind: JG wins
LA-Det-LA: IS wins
LA-Det-Det: IS wins
LA-Ind-LA: IS wins
LA-Ind-Ind: JG wins, unless LA beats Minn in 7
and Ind beats Det in 5, in
which case we'd have a tie
I did this fast, so I can't vouch for it's accuracy 100%, but I'm pretty certain that this is how it plays out
