Surely you’ve thought about it.

If you’re a fan of one of the top four teams in the B1G East — yes, I said four — the what-if scenarios have been running through your mind.

What if Ohio State loses to Michigan State but beats Michigan?

What if Michigan State loses to Ohio State but Michigan beats Ohio State?

What if Penn State wins out and Ohio State loses out?

If that happens, we’ll be looking at a complete and total mess in the B1G East. That would potentially shape up to be a four-way tie in which the highest ranked team in the College Football Playoff poll would represent the B1G in the conference title game based on the fifth tie-breaker.

So here’s your complete guide to all the B1G East scenarios, as brought to you by a user on College Football Reddit.

And if you want to know how exactly that four-way tie would shake out, here’s the official B1G rule book.

The following procedure will determine the representative from each division in the event of a tie:

(a)    If two teams are tied, the winner of the game between the two tied teams shall be the representative.
(b)    If three or more teams are tied, steps 1 through 7 will be followed until a determination is made.  If only two teams remain tied after any step, the winner of the game between the two tied teams shall be the representative.
1.    The records of the three tied teams will be compared against each other.
2.    The records of the three tied teams will be compared within their division.
3.    The records of the three teams will be compared against the next highest placed teams in their division in order of finish (4, 5, 6, and 7).
4.    The records of the three teams will be compared against all common conference opponents.
5.    The highest ranked team in the first College Football Playoff poll following the completion of Big Ten regular season conference play shall be the representative in the Big Ten Championship Game, unless the two highest ranked tied teams are ranked within one spot of each other in the College Football Playoff poll.  In this case, the head-to-head results of the top two ranked tied teams shall determine the representative in the Big Ten Championship Game.
6.    The team with the best overall winning percentage [excluding exempted games] shall be the representative.
7.    The representative will be chosen by random draw.
