the short version is this:
there seems to be no possibility of a 4 way tie.
in the event of a 3 way tie, Auburn will smoke bama, MSU and OM.
also, in the event of a 3 way tie, OM will not win out over anyone....
summary: MSU and Bammers best hope (in the event of a tie) is that the tie is with OM (and not AU)...
