The yellow tick is USC's August 13, 2025 preseason SP+ rating (+13.2) — the last preseason release before Week 1, from Bill Connelly / ESPN. The dark bar is the final 2025 SP+ (Connelly, post-championship). Both mapped to the 0–100 scale by score = 50 + SP+ × (50/35), clamped [1, 99]. The gap between them is Δ: +5.3. Δ banded A through F gives the letter grade.
A C means USC finished within a narrow band of the projection (Δ +5.3, band −6 to +8). The season the projection described.
Ceiling grade: C · secondary lens · 17% of upside headroom used. Δ divided by the room USC had to move (upside if Δ is positive, downside if negative). Ceiling normalizes for projection height: a projection-90 team has 10 points of upside room, a projection-50 team has 50.
The letter grade always records the same relationship: realized minus projection, banded A through F. A team can sit in the Elite tier and still receive a D. LSU in 2025 is that case.

Portal moves are weighted by recruiting stars, position (QB and skill positions weighted higher), and eligibility. Withdrawn entrants are excluded. The z-score is normalized across teams appearing in the 2025 portal cycle (context).
Returning production (2025): 37% of prior-year PPA back on the field (Bill Connelly's percentPPA metric via CFBD). This is a narrative reference — the 2025 grade itself is Δ vs preseason SP+ only.
