It’s the halfway point of the regular season for most Big Ten teams, and the East division has settled into two tiers, comprised of exactly the teams everyone expected when the new format was introduced prior to last season. Ohio State and Michigan are joined by Michigan State and Penn State at the top of what could turn out to be the toughest single division in college football. Today is the first of three weekends this season where these four teams will be playing each other. The second and third rounds will close out the regular season, so while today’s winners will get an early jump on the division title, there will be plenty of time for the losers to get back into the race.
