Michigan Football By the Numbers: Wisconsin


The Wolverines put together a tremendous all-around performance to dispatch of the Wisconsin Badgers. We must give credit where it’s due, and I think that starts with Ed Warriner and the Offensive Line, with a tip of the cap to Don Brown and Greg Mattison. Shea Patterson is in a lot of headlines, but Warriner and his group are the biggest reason Michigan’s offense has improved from 85th in the S&P+ in 2017 to 27th in 2018 through Week 7. Defensively, Michigan retained the #1 S&P+ defensive ranking after clamping down on what was the 8th ranked S&P+ Badgers’ offense, despite Rashan Gary missing his second consecutive game due to injury.

What is S&P+
The original system was based on Success rate and equivalent Points per play. It was an attempt at an OPS-style measure for football, a look at both efficiency and explosiveness. As so many things do, however, it has grown more complicated.In its current state, S&P+ is based around the core concepts of the Five Factors of winning football: efficiency, explosiveness, field position, finishing drives, and turnoversFull Explanation 

*I found and corrected a bug in my modified S&P+ excel file that affected IsoPPP.  I have corrected previous weeks’ data in my workbook also.


The simplest understanding of this game is this: Michigan did to Wisconsin what we’ve seen the Badgers due to B1G Ten opponents for a decade, they executed. Even though everyone knew what Jim Harbaugh wanted to do on offense, the players were able to execute successfully anyway. Coming in, Michigan’s average success rate was 49.2%. They managed 45.6% success against Wisconsin. In terms of explosiveness, Expected Points / Play (PPP) is a metric that quantifies each play based on starting yard line versus ending yard line. IsoPPP looks only at successful play, which helps separate it from the Success Rate metric. Michigan’s average in PPP coming in was 0.49. They were above average versus the Badgers at 0.51. The offense was also slightly above (0.98) their season average (0.92) in IsoPPP. For me, the most remarkable offensive characteristic from this encouraging performance was that we can definitively say the game went according to plan. We are starting to see Jim Harbaugh’s offensive vision come into focus.


In year three under Don Brown, it’s quite a challenge to avoid sounding like a broken record as I compliment the defensive unit week in and week out. Saturday night on the national stage in prime time, versus the 8th ranked S&P+ offense coming in, was precisely the defensive performance that Harbaugh’s staff has been game planning around. Wisconsin had more success than average versus the Wolverine defense, but never enough to flip field position or to create scoring opportunities. Coming into the game, opponents were averaging 33.2% success rate, 0.29 PPP, and 0.83 IsoPPP against Michigan. The physical Wisconsin offense established a 38% success rate, 0.42 PPP, and 1.01 IsoPPP. However, after the Badgers scored to tie the game 7-7 in the second quarter, their next six drives went: Punt, INT, Punt, Punt, Punt, INT for TD.


Overall: 20.4, 4th (up 1)

M Defense 14.6 (1st) vs. O Offense 28.1 (75th), Midpoint: 21.35

My midpoint S&P+ method gives a 6.05 point edge to Michigan. The Spartan defense versus Wolverine offense is a key match-up of similarly ranked units. Defensively, Michigan will have to weather the storm as MSU empties the entire bag of tricks.

GAME WEEK UPDATE: Can Michigan pack their balanced, complementary game plan with them for a short trip to East Lansing? The struggles on the road are still worrisome, and we know the Spartans will come out firing hay-makers. I expect Pep Hamilton and Shea Patterson to expose a weak MSU secondary. However, if the weather gets sloppy, this could turn into an old-fashion battle of will power.

Now we have finally seen the Michigan game plan of an efficient offense complementing a dominant defense work to effectively grind a solid opponent into powder. There is still a significant amount of work to be done, and it is crucial for the Wolverines to show they can execute the game plan at a similar high level in a hostile environment in East Lansing this week.
