For your talking point pleasure:
According to the various services that rate schedule strength, Alabama's schedule so far has been tougher than the average team's schedule, Oregon's schedule has been easier than the average team's schedule. (I'm saying that with 120 teams, 60th is average.)

Alabama 35th-toughest schedule
Oregon 74th-toughest schedule

This 31st-78th is actually probably more accurate than the 35th-74th I'm leading with.
