2018–2026 · 9 seasonsRecord 82-12National titles 1Great seasons 8 (top ~7% of all teams that year)
  • Rating 91: his whole career, recent seasons weighted most, measured as how far his teams stood above their era, crediting him with half of what each program already was when he arrived (about the share that, historically, follows a coach to his next job), fading as the program becomes his own.
  • Peak 94: best five-season stretch, 2022–2026 at Ohio State (48-8, 5 top-10 seasons by team strength, 1 national title), taking over already a national power.
  • Career 81 (#48 since 1936): total accomplishment over 9 seasons (82-12), 1 national title, 8 elite seasons; full credit for the program he inherited.
  • All of it at one program (Ohio State) — unproven elsewhere; historically about half of a coach's lift carries to a new job.
Over expectation · 2016 on85Results against what his rosters' talent predicted (program lift, evaluation, recruiting, staff building, game management).

Rating = who he is: his whole head-coaching career (since 1936), weighted toward recent years — how far his teams stood above their contemporaries, how much he lifted programs, his great seasons and titles. Form = the last two seasons. Career = the all-time ranking number.
