I was thinking about this too as I was writing out the post and I could not come to a clear conclusion. Maybe these numbers can help us reach the answer to the question you posed. This is what I have:
Wisconsin is ranked 35th in the country in tackles for loss, and 21st in the country in sacks. Put into perspective, Ohio State is ranked 8th and 11th respectively.
The stats will show that Wisconsin this year has allowed an average of 4.2 yards per play (#5), whether it be 1st, 2nd, or 3rd down. This does not tell us very much though. But for perspective, in this statistic Penn State comes in at #1 in the country, allowing 4 yards per play, and Michigan State ranks 15th at 4.7 yards/play, which is the same yards allowed per play by our Buckeyes. Now, take that into account and consider that:
1) they (they being Wisconsin) are allowing only 13.5 first downs per game (#1 in the country, PSU is #2 and MSU is #3, Ohio St. #23 w/19);
2) they allow 3.1 yards per rushing attempt (OSU allows 4 yards per attempt)
3) they allow 5.7 rushing first downs per game (MSU and PSU 1 and 2 respectively...OSU #39)
4) they allow 6.2 yards per pass attempt (#19...OSU sits at #13 w/ 6 yards per pass and MSU also allows only 6 yards per pass)
5) and they allow 6.4 passing first downs per game
After all of this data is processed, I really can't say I have a definitive answer to your question...what can you get it by looking at the numbers?
