The live grade measures current in-season SP+ (Bill Connelly, via CFBD) against Boise State's frozen August projection of 57.1 — the same number that set the 2026 tier. Same mapping (score = 50 + SP+ × (50/35)) and the same A–F Δ bands as the 2025 grade below. It recomputes each week as SP+ updates; the projection and tier do not. Early in the season, in-season SP+ still leans heavily on its preseason priors, so most live grades start near C and drift as results accumulate.

The yellow tick is Boise State's August 13, 2025 preseason SP+ rating (+10.0) — 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: −9.9. Δ banded A through F gives the letter grade.
A D means Boise State finished between 6 and 18 points below the projection (Δ −9.9). Short of the number, and not narrowly.
Floor grade: D · secondary lens · 15% of downside headroom used. Δ divided by the room Boise State had to fall from projection 64.3 toward 0. A team at projection 64.3 had 64.3 points of downside room; a proj-90 team would have had 90.
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 Withdrawn entrants are excluded.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): 58% 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.
