It's called advancing the discussion forward. I think the board understands the validity of F+ now so instead of being bogged down in lengthy arguments about the validity of the system we can advance the discussion forward.
F+ is powerful tool to assess the landscape of college football but its an automated formula/algorithm. You rely on the system where its strong (ranking all 130+ teams by their offensive, defensive, and special teams production/ranking them overall) but compensate for it where its weak or has blind spots entirely (individual matchups, roster attrition, team talent, etc.)
Also, this would be NDs best opponent all season, I agree. But that says more about the lack of quality of NDs schedule more than anything else.
