Back to the present:
If Ohio State has any advantage today and this weekend it is that they are the only remaining team that is playing to extend their season. The other seven are, IMHO probably all tournament locks. Ohio State is already in a win-or-go-home situation.
Ohio State's obvious disadvantage is that they are already playing their third game in three days. PU, MSU, NU, and IU are playing their first game today while RU, PSU, and UMD are playing their second.
