So if we decide we're going to care about this (apparently I care enough to have looked this up), then we care (more than just conference affiliation) that Illinois beats USF this weekend.
Because SMU had already lost, TCU has only their home territory to give this Saturday. The Buckeyes can pick up nothing next week vs Tulane as neither the wave nor their week 3 opponent (UAB) has any territory.
But if the Illini can hang on against the Bulls, that puts the Buckeyes in position to pick up a fair amount of territory by beating Penn State (who will presumably have beaten the Illini by then). Everything currently held by USF, Illinois and Penn State would then belong to OSU.
We can pick up a little the following week if the Hoosiers can hold serve between now and then (vs Ball State, MSU and Rutgers).
We likely pick up nothing the following week, as the Gophers will probably have just lost to the Hawkeyes. It's a homegame for Minnesota, but Iowa fans take over their place nearly as much as we take over Bloomington. If the Gophers can hold serve though, we pick up quite a bonanza that week.
There's precious little that we can pick up after that barring some major upsets, and that holds true until the conference championship game, at which point we might pick up less than you might think from Wisconsin.
Neither Wisconsin nor Iowa stand to gain anything in Week 3, and play each other in Week 4. After that, due to the way the schedule plays out, both could win out from there without picking up any territory, as all of the teams they play have a good chance of losing territory by then and then not having a chance to gain any back.
Long story short, it's possible the Buckeyes could win out and have only the following to show for it after the first Saturday in December:
Everything currently held by:
Wisconsin
Iowa
Penn State
Indiana if they beat MSU
and USF and Illinois if the Illini can pull it off this weekend.
