Who Chesterton is on defense
3-4 / Under · 61%
The base front across 109 graded snaps. Under sets to the TE/wing side — nose 1-tech, ends in 5s, OLBs can walk up. n=109 HIGH
C0-lean · split-field C4/C1
Combined C0 reads 74% but that's skewed by one game. WK8 (their true base): ~41% C0, ~43% split-field C4/C1, ~14% C4. MED
Pressure · 16–19%
Mike is the primary pressure (10 of the tagged blitzes) + Double-A gap, occasional Sam/Will edge. MED
DBs don't collision
All four grade negative on Collision. Corners play under-inside. Free releases are there all night. MED
Data honesty — read this first
- Two games, 109 graded snaps — WK8 CP @ Chesterton (50, regular season) + WK10 LaPorte @ Chesterton (59, sectional). Small sample; every added game sharpens it.
- The two games are two different defenses. WK8 = the true base (3-4, mixed coverage). WK10 = a wrinkle game (52/Bear, near-pure C0) — their own tagger flagged the front as "different than the rest of the season." Weight WK8 as identity.
- R4 DB grades are 2025 role tendencies. The secondary reshuffled for 2026 (Prater & Robinson moved CB→S; Reed & Smith are the corners) — confirm on this year's film.
- No snap-level export was retained, so there are no by-down / red-zone / formation cuts on this page — only combined rates. See the Better Data tab for what one Hudl export unlocks.
- Confidence: HIGH = clear majority of the sample · MED = film-read from a 2-game sample. Treat MED as a lead to confirm, not a law.
Key findings
Two games = two defenses. WK8 is who they are; WK10 was a plan.
WK8: 3-4/Under fronts, mixed coverage. WK10 sectional: 52/Bear "double-3" + near-pure Cover 0 (98%). Prep the base first; carry answers for the wrinkle. n=109 HIGH
// rebuild in Hudl: WK8 CP game vs WK10 LaPorte game, DEF FRONT column
Base front: 3-4 / 3-4 Under / Bump = 61% — Under sets to the TE/wing.
52 (25%) + Bear (15%) = 40%, but concentrated in the LaPorte sectional. Run-game rules install vs 3-4 and Under first. n=109 HIGH
They are NOT a pure Cover 0 team — they carry a split-field package.
"C4 Special" (quarters to one side / man the other) was 43% of the CP game, plus straight C4 (~14%). Expect man AND quarters in the same drive. Motion declares it. WK8 n=50 MED
Pressure ~16–19%: Mike first, Double-A second.
Roughly one pressure every 5–6 snaps. The OLB peels to carry the RB swing — the back in the flat is NOT a free outlet vs pressure. MED
No DB collisions well, and the corners don't jam.
All four DBs grade negative on Collision. Free-release timing routes are open all game; both corners are first-year starters in 2026. MED
Pre-snap tells — If / Then
Film-read tells from a 2-game sample — leads to confirm early in the game, not threshold-verified rates.
IF you declare a TE/wing side → THEN the Under front sets to it: nose to the 1, ends in 5s. Your strength call moves their front. HIGH
IF you motion → THEN the coverage declares: travel = C0/man side, bump = the quarters half of C4 Special. Motion on early downs to build the picture. MED
IF they show 52 / Bear "double-3" → THEN wrinkle-game alert: in the LaPorte plan that came with near-pure Cover 0. Check the man-beater menu on. MED
IF the RB swings vs pressure → THEN the OLB peels to carry him. Hot answers live inside (quick game), not in the flat. MED
IF 3rd & medium+ → THEN expect the pressure package (Mike / Double-A) with C0 behind it. Protection check + hot first. MED
Situational call sheet — starter
Their look and our answer in our terms. Built from the film scout — no by-down data exists yet (see Better Data), so this is the starter, not the law.
| Situation | Their likely look | Our answer (our terms) | Why |
|---|---|---|---|
| Base downs — run | 3-4 / 3-4 Under (Under to TE/wing) | Base run rules vs 3-4 & Under · combo the nose (#47 Vaiolo) | 61% of fronts. 52/Bear only as a change-up look. |
| vs Cover 0 man | C0 pressure-man (WK10: 98%) | Michigan (Mesh) rubs · Demon (Post-Corner) · A Baylor (Vert Choice) | Verticals on the safeties — neither collisions. |
| vs C4 Special / quarters | Quarters one side, man the other (43% of WK8) | Gator (Snag) · Wave (Flood) · Cowboy (Waggle) | Find grass; hold the safety with a seam, throw underneath. |
| vs pressure (Mike / Double-A) | ~1 in 5–6 snaps, C0 behind it | Quick game + hot answer · screens/draws at the interior | OLB peels to the swing — don't lean on the RB flat. |
| Wrinkle alert (52 / Bear) | Their LaPorte special: double-3 front + C0 | Man-beater menu ON · free-release timing routes | Treat as a plan they can bring back, not their identity. |
What beats each coverage
vs Cover 0 man (their lean)
Michigan (Mesh) rubs · Demon (Post-Corner) · A Baylor (Vert Choice) at the best matchup. Verticals at both safeties — neither collisions, both grade negative on closure. The corners don't jam, so free-release timing routes hit on schedule.vs the split-field C4/C1 ("C4 Special")
Quarters to one side, man to the other — read the halves separately. Gator (Snag) · Wave (Flood) · Cowboy (Waggle) into the quarters half; hold the safety with a seam and throw underneath him. Man-beaters still live to the man half.The declare rule
Motion pre-snap on early downs: travel = man, bump/stay = zone half. Build the picture in the first two drives, then call the menu with certainty.The pressure profile
~16–19%
Pressure rate across both games — about one every 5–6 snaps.
Mike #7
Westerlund (all-state) is the primary pressure — 10 of the tagged blitzes run through him.
Double-A
The second family. Occasional Sam/Will edge behind it.
The peel
OLB carries the RB swing (WK10). The flat is not your free outlet vs pressure.
The answer: quick game + a hot answer vs Mike / Double-A every snap they're on the field. Screens and draws punish the interior pressure. ID #7 (Mike) and #47 (nose, 245) every play.
DB Attack Matrix
2026 personnel by role. Grades are '25 role tendencies (secondary reshuffled — Prater & Robinson moved CB→S) — confirm on this year's film.
| DB | Leverage | '25 role tendency | Attack |
|---|---|---|---|
| Field CB · #26 Reed new starter | Under-inside | Collision − · Closure − | Out / comeback / back-shoulder · free-release timing (corners don't jam) |
| Boundary CB · #5 Smith Jr · softest | Under-inside | Collision − | Go at the young corner — free-release timing, out/comeback, double-move if he sits |
| Field S · #23 Prater was CB | Over-inside | Doesn't collision | A Baylor (Vert Choice) seam / Demon (Post-Corner) through his zone; win the matchup in man |
| Boundary S · #12 Robinson was CB | Mixed | Doesn't collision | Attack vertically — A Baylor seam / Demon. Man or the quarters half |
The green spots: both corners are first-year starters — hammer the field corner (#26) and go at the young boundary corner (#5, Jr).

Attack: C0 man mixed with split-field C4/C1 · hit the field corner (#26 Reed) on out/comeback, verticals on both safeties · beat the Mike + Double-A pressure · ID #7 Westerlund (Mike) & #47 Vaiolo (nose). Softest matchup: #5 Smith (Jr, boundary CB).
The Plan
⚠ This section is interpretation — the AI Coordinator's Read. Everything above it is the film scout's computed picture; every claim here ties back to it.
- Install the run game vs 3-4 / 3-4 Under first (61% of fronts). Combo the nose (#47 Vaiolo, 245). Keep a 52/Bear answer in the pocket, not the plan.
- Carry BOTH menus: man-beaters (Michigan rubs · Demon · A Baylor) and quarters-beaters (Gator · Wave · Cowboy). They mix C0 with split-field C4/C1 — motion declares which half you're in.
- Attack the corners and the safeties' hands: both corners are first-year starters who don't jam; no DB collisions well. Free-release timing routes + verticals at the safeties.
- Beat Mike + Double-A before it beats you: hot/sight answers on every call, quick game ready, screens/draws at the interior. The RB swing is covered — the OLB peels.
- First two drives are recon: motion every early down, confirm the '25 tendencies against this year's film, then call the second half of the sheet with conviction.
