Crunching some numbers since I'm bored and thought this was an interesting topic:
Since the 2nd half of the Ohio State game:
24 points allowed [roughly 9 per game]
521 Yards allowed [52.1 yards per quarter]
Opposing QBs: 21/55 [38%], 221 yards, 0 TDs 2 INTs
+3 Turnover Differential
50 consecutive minutes without allowing a score [10:56 3rd qtr tOSU--6:45 3rd Qtr Minnesota]
