I chased down some numbers.
In PSU's current 75 dual winning streak PSU has outscored its opponents 34.4 - 6.9 on average, for an average margin of victory of 27.5
In Iowa's 69 dual winning streak Iowa outscored its opponents 33.0 - 6.7 on average, for an average margin of victory of 26.3
Iowa's Streak
- Ten of Iowa's wins came against non-D1 schools, but they did beat PSU three times during the streak (and once more during the 84 dual unbeaten streak).
- Their favorite punching bag was Minnesota. They beat the Golden Gophers five times in the streak (and a sixth in the unbeaten streak).
- Their biggest margin of victory was a 57-0 win over Cornell College.
- They also beat Iowa Lakes and Iowa Central 52-0.
- There were a whopping 19 shutouts during the streak (and a 20th during the unbeaten streak).
Penn State's Streak
- PSU's favorite punching bags are Maryland and Ohio State whom they have beaten six times each.
- PSU's largest margins of victory came over Edinboro and Michigan State (55-0).
- PSU has had 12 shutouts during the streak.
I have not looked at the OSU streak yet because scoring rules and numbers of weights varied significantly making comparisons on scores pretty meaningless.
