Best comparisons are the Conf-Only Stats as both PSU and MSU play a b1g East Division Sched.....and we're 8 games deep in a 9 game Conf Season....
To wit....MSU has a poor Run Defense - 10th in the Conf giving up 178 rushing yards per b1g contest to-date. However, MSU has a very good Pass Defense giving up only 183 passing yards per b1g game - albeit, a fairly high-risk pass defense that features a lot of man coverage as evidenced by their very poor TDs surrendered to INTs gained ratio (12 TDs to only 6 INTs or a 2-to-1 ratio of TDs surrendered vs INTs. Their 12 TDs surrendered is also pretty poor on an absolute basis being tied for the 9th/10th most TDs surrendered in b1g play only Indiana (13), Minny (13), Purdue (14) and Rutgers (15) surrendered more.). Given the above combination, MSU is very middle of the road in terms of "Total Defense" (i.e., avg yards per b1g game surrendered) at 7th place in the Conference surrendering 361 yards per b1g game - however, and it's a big however, they are bottom-half defense in YPP (average yards given up per snap) and TDs allowed, which are often a better barometer of how good the defense really is - MSU tied for 9th/10th with 5.4 YPP allowed and was 9th in TDs allowed, 25, in b1g play.
IOW, MSU's defense is not as good as the "Total Defense" numbers would suggest - they're somewhat similar to Iowa's defense in this regard.
OTOH, PSU's offense ranks 3rd in Scoring Offense (36 PPG), 3rd in Total Offense (441 YPG) and 3rd in Rushing Offense (217 YPG) in b1g play. Clear advantage to PSU albeit dependent on whether PSU is down 0, 1 or 2 starting OL which we won't know until game-time.
On the other side of the ball, PSU's Defense ranks 4th in YPP surrendered at only 4.8 YPP in b1g play, which is a very, very good number (anything under 5.0 is very good - 5.5 is about the "national average") - the three defenses in front of PSU in b1g play are scUM at 3.9 YPP allowed, daO$U at 4.4 YPP and Wisconsin at 4.6 YPP. The "median" stat for the entire conference is 5.2 (Iowa and Indiana) - the worst 4 are 5.5 (ILL), 6.2 (UMd), 6.6 (Buttgers) and 7.0 (PurDon't). So as you can see, PSU's 4.8 YPP Defense is very, very good, while MSU's 5.4 YPP Defense is very "Ill-noise like".... MSU's offense, led by their running game, is top-half coming in 5th (416 ypg) in b1g play, but their "Scoring Offense" is very average coming in 7th at 25 ppg. I give the advantage to PSU's Defense which has played better and better virtually every week of the season.
PSU also holds the advantage on Special Teams and "intangibles" imho.....so they're you have it, a clean sweep:
- PSU OFF has advantage over MSU DEF (assuming we are only down 1 starting OL)
- PSU DEF has advantage over MSU OFF
- Advantage to PSU's Special Teams, and finally
- Advantage to PSU on "intangibles" as PSU clearly has "more to play for" and they're playing @ The Beav where PSU is 6-0 this year (including a win over #2 daO$U and a blowout over Iowa) and 11-1 over the past two seasons to-date.
