I haven't seen a single modeling site with a 11-1 ND team out of the playoffs. ND is ~60% to make playoff ≠ 11-1 ND 60% to make it. The 40% is because ND still plays 2 ranked opponents and USC.
The sportswriters who have an 11-1 ND out of the playoffs fall into 3 categories.
1. Clickbait hacks who are too stupid to understand math and know any better.
2. Clickbait hacks who know better but need clicks.
3. Moronic mama's basement-livin' bloggers with a platform for some reason.
