OFFENSE:
Ohio State: #1 (47.2 ppg)
Michigan: #15 (36.9 ppg)
DEFENSE:
Ohio State: #16 (19.0 ppg)
Michigan: #7 (16.3 ppg)
Their offense isn't "close" to ours (10.3 ppg less), and their defense is three points per game better (16.3 vs 19.0). But that includes all games including the early out of conference games. Let's just look at common opponents:
Rutgers:
Ohio State 52, Rutgers 13
Michigan 20, Rutgers 13
Nebraska:
Ohio State 26, Nebraska 17
Michigan 32, Nebraska 29
Michigan State:
Ohio State 56, Michigan State 7
Michigan State 37, Michigan 33
Indiana:
Ohio State 54, Indiana 7
Michigan 29, Indiana 7
Penn State:
Ohio State 33, Penn State 24
Michigan 21, Penn State 17
Maryland:
Ohio State 66, Maryland 17
Michigan 59, Maryland 18
We crushed three opponents while Michigan won two in normal fashion (Rutgers and Indiana) and lost one (Michigan State). Two other games (Penn State and Nebraska) we both won close games, and in the sixth game we both blew out Maryland. We beat all six common opponents by more than Michigan did...all six. The average score for the six games: Ohio State 48-14, Michigan 27-20.
