Rating 55: 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 55: best five-season stretch, 1988–1990 at Tulane (13-21), taking over an average program.

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.
