i agree with you that this years schedule was harder to go 12-0 than last years... agree 100%Id rather play 2 top ten teams 1 non p5 and 11 unranked opponents over 4 ranked teams and 2 top 10 p5 teams any day
Anyone who thinks the first one is more difficult needs to rework their formula.
But this years schedule was also easier to go 8-4 than last year.. both can be true with the formula. The formulas for SOS don't say which schedule is hardest to go 12-0, it's who played the toughest teams game in and game out full season.
