Doing a quick and dirty comparison of simple scoring differentials you see that ISU is something like a 3 TD better game at home than away and KU is something like 3 1/2 TDs better at home than away. These numbers can be a little bit skewed if you don't account for the performance of individual teams, so I tried to tackle this question and found some pretty crazy results...of which feel free to skip to my follow up post for those results...but first going to try and explain what I mean for these results...
The main point will be when I say below that KU is this many points better at home, it doesn't mean they score that much more than the opponent at home versus away, it's a combination of points scored and points allowed.
What I did was tried to figure out how each team that played either KU or ISU did against these schools (not counting non-D1 schools in these numbers) without the KU or ISU game and then compared those average results to how they did against KU or ISU.
That means I manually pulled the data (which sucked) for both of the D1 8 teams that ISU and KU have played separately (16 total teams), considered every D1 game those 16 teams have played so far this year (between 7 and 9 games per team, total of 130 games), and input or calculated a total of 34 variables per game per team.
Once I had the averages of these variables, calculated the difference between these variables for the season average from what they did against ISU or KU. I combined the differences for KU and then again for ISU where I then averaged these differentials for both ISU and KU to have two separate sets of home and away values. Once I had these value, I then subtracted the home and away values for each school to get an away/home indicator of if they were doing better at home or not.
So that's a little bit messy, thus let's look at an example of what I mean.
Take the Memphis/KU game. Memphis won that game 43 - 7, but taking out the KU game, Memphis has scored roughly 39 points per game this season and allowed roughly 29 points per game this season. Since Memphis scored 4 more points against KU than the average of the other teams and allowed 22 points less to KU than other teams, this results in a 26 point differential in favor of Memphis (4 + 22 = 26).
Now take the TCU game. TCU won that game 24 - 23, but taking out the KU game, TCU has scored roughly 36 points per game and allowed 28 points per game. Since TCU scored 12 points less against KU than they did other teams on average but allowed 5 points less than they did other teams on average, this results in a 7 point differential in favor of KU (12 - 5 = 7).
Now that I got that stuff out of the way...the results...in the next post...
