Hawkeyes fans will be hoping that Petras follows a similar trajectory to TCU quarterback Max Duggan, who took his play to new heights from 2019 to 2020. Duggan’s passing grade in 2019 was 57.0, right next to Petras’ 56.9 mark in 2020. Duggan was able to cut down on turnover-worthy plays and up his accuracy and big-time throw rate slightly to push his grade to 69.9. - PFF College
