- Rating 62: 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 62: best five-season stretch, 2012–2024 at Penn State and Boston College (22-15).
