7-8 with 1967 resources is possibly better than the current 12-6 team.No.
1967 Dave McCuskey "led" Iowa to a 7-8 dual record. Iowa would build towards becoming a powerhouse program shortly after that and wouldn't lose more than 5 duals in a year again until Jim Zalesky saw Iowa go 11-7 back in 2006. Tom Brands took over the following year.
So Iowa's 12-6 dual record this season is their worst in only 20 years.
