Yes, the result was certainly disappointing against Ohio State, but it was a great atmosphere and an exciting and hard-fought game on both sides. Now, some stats to chew on going into a challenging game in Madison.
Northwestern has scored 30 or more points in 7 consecutive games, which is the longest such streak in school history. The previous longest streak was 3 games of 30 or more points in a game, which NU has done 6 times (1905, 1962, 2000, 2004-2005, 2005, 2010). All-time, NU is 149-24-1 when scoring 30 or more points in a game (0.856).
Since 1995, Northwestern is 5-0 vs. Wisconsin when scoring 30 or more points and 1-6 when scoring fewer than 30 (the only win in the latter category came in 2003 when NU won 16-7).
The Wildcats will be playing in their 6th consecutive non-11AM CT kickoff, and that streak will end as the Minnesota game will kick off at 11AM (on ESPN2). This matches the longest such streak since 1995, which occurred in 2005-06, although that includes 2 non-televised home games that kicked off at 1PM CT. Otherwise, the longest such streak was 4 games from 1995-96 that included the Rose Bowl.
This was the first time since the loss to Iowa on 11/11/2000 that Northwestern lost a game and remained ranked in both major polls (AP & Coaches); that time, NU fell from 12/18 to 23/24 (this time around, NU fell from 16/15 to 19/18). NU has been ranked in both polls for 10 consecutive poll releases, which is the longest such streak since the 1996 season (when NU was ranked in both for 11 straight releases).
As mentioned by Rodger, Northwestern (a ranked team) is an underdog against Wisconsin, who is currently not ranked (receiving votes in both polls). This is the 5th time since 1995 that this has occurred, all of them have been Big Ten road games, and this is the 2nd time NU will be heading to Madison under this scenario. In the previous occasions, the 'Cats have gone 2-2.
Under Fitz, Northwestern is 6-6 when it is another team's homecoming opponent, though the 'Cats have won at least 1 such game each season dating back to 2008 (the Wisconsin game is the only game this season when NU will serve in this role).
The Wildcats have now held the lead in the fourth quarter in 18 consecutive games (NU is 14-4 in those games).
Under Coach Fitz, NU is 14-14 in Big Ten road games. NU is 15-13 under Fitz in games played on artificial turf (17-11 ATS, including a current 6 game winning streak ATS on turf). All-time, Northwestern is 15-4 as a ranked (AP) team playing on artificial turf.
