How will we know? On paper, the offenses on the schedule should be much better than those played in 2019.
That 2019 schedule had some truly inept offenses in Oregon State, Cal, Arizona and Colorado. Scheduling luck catching Arizona State missing half their OLine during a freezing rain storm, UCLA without DTR, Washington in a down year and missing Oregon.
This year’s team could give up 100 more yards and 10 points a game and you could make the argument that they were as least as good statistically based on quality of opponent.
