If you carefully read
the B1G tiebreakers and think through the implications and scenarios you will eventually discover that the one listed as "cumulative conference record of conference opponents" is extremely likely to be determinative.
H2H is first in a two-team tie but that obviously only applies if the two teams played each other. Since we have 18 teams and nine conference games that isn't all that likely.
In a tie involving three or more teams, H2H...2H will almost never help because it only applies if they all played each other or if one played and defeated each of the others.
After H2H they go through record against common opponents and record against the best (or next best) team then the next, etc but those will not usually help because of the variation in schedules so then you get to what is effectively SoS.
Thus, league winning percentage of league opponents will usually break ties and here it is so far:
Obviously it is early and there is a LOT of football to be played but it looks like Penn State and Oregon have the best tiebreaker situations of the contenders.
FWIW: I don't think Ohio State's opponents are actually THAT bad. They look really bad right now but part of that is because two good teams that Ohio State plays (PSU, UDub) started their conference campaigns with REALLY tough games (vsOre, @tOSU) and lost so they are each 0-1.
For reference:
Last year Oregon was outright #1 so they got the home jerseys in the CG but Indiana and Penn State were tied for the second spot. IU and PSU were both 8-1 with each of them losing to Ohio State. They didn't play each other and lost to the same team so the tie was broken based on SoS where IU was not even close.
