2012It has been 3 times in the past 8 years that Oh St has not won the Big 10 East. Mich St (2015) & Penn St (2016) also accomplished it in leading up to the East's 8-0 record. So I suppose in addition to Mich it's really a 4 team issue.
2013
2014
Scholarship reductions and probation
2015 and 2016 were when those three classes were up classmen.
2011 - 6-7 first year after the blowup…interim coach
2012 - 12-0 (wisconsin wins big ten at 7-5)
2013 - 12-2 (lost big ten title game to Michigan state)
2014 - 14-1 (Ohio state big ten and national champion)
2015 - 12-1 (Michigan state beats Iowa by 3 in big ten title game…Ohio state finishes 4)
2016 - 11-2 (Penn state wins big ten but Ohio state goes to playoff)
2017 - 12-2 (Ohio state beats wisconsin by 6 in big ten title game)
2018, 2019, 2020 - all Ohio state big ten titles
so basically, this is the first year since the big ten title game was invented when one of the two following things isn’t true:
Ohio state with interim coach, on scholarship reductions OR With a smaller senior class due to earlier restrictions
OR
Ohio state winning the championship.
even when they were impacted by 2010 scandal…
79-15 with 2 big ten titles in 7 seasons
Excluding the 6-7 under fickle
73-8 with 2 big ten titles and 3 division titles in 6 years while on probation or with smaller senior classes due to probation.
in those 7 seasons they were impacted by probation:
Ohio state 2
Michigan state 2
Penn state 1
Wisconsin 2 (one of these seasons wisconsin was 7-5 and Ohio state was 12-0 but ineligible for championship game)
