A pregame research note built from the stored 2026–27 forecast, its stored factors and the questions still waiting for film or roster confirmation.

UMass Lowell 71.4 · American 75.9
Primary preseason estimate from the published efficiency model. The range describes held-out model error, not a promise about the final score.
What this game analysis uses.
Read the forecast, historical workload, shot map and roster signals in separate columns. A model edition identifies the registered estimate; an internal receipt identifies the retained data edition. Missing or mismatched evidence stays visible as unavailable.

This table documents provenance and joins. It does not turn a source listing into an availability decision, and it does not add a second forecast to the stored model.
How the projected score is built.
This table reconstructs the stored ridge model from its published coefficient arrays. Each efficiency term is points per 100 possessions; the final score is efficiency × projected pace ÷ 100. It is an explanation of the estimate, not an additional forecast.
| Term | UMass Lowell | American |
|---|---|---|
| League baseline | 107.03 | 107.03 |
| Own offense effect | -2.51 | -2.70 |
| Opponent defense effect | +3.49 | +5.44 |
| Venue effect | -2.46 | +2.46 |
| Projected efficiency | 105.55 | 112.23 |
| Projected pace | 67.64 | 67.64 |
| Score from equation | 71.40 | 75.91 |
A neutral-site game has zero venue effect. A missing or edition-mismatched coefficient set suppresses this table rather than presenting stale arithmetic.
How much has this model missed?
These held-out results describe the forecast system behind this notebook. They are a calibration reference for the range, not a guarantee about this game and not evidence of a market edge.
Training seasons: 2023, 2024, 2025, 2026 · constant home-margin baseline MAE: 12.0 pts. The test season remains outside model fitting and calibration.
Turn the forecast into questions.
Read these in order before opening the deeper tables. Each row is arithmetic over the stored forecast, exact team ratings, matchup factors or matched roster scenario. It does not add a new model.
| Read | Finding | Stored evidence | Question to take to film |
|---|---|---|---|
| Step 1Start with the range | Both teams remain inside the 80% margin range | American is the baseline side by 4.5 points; the stored home-margin range is -11.4 to +20.4. | Which early matchup signal would make you update away from the baseline? |
| Step 2Find the pressure point | UMass Lowell owns the largest stored factor edge | offensive rebound rate · 5.0 percentage points toward UMass Lowell. | Which actions and lineups are creating that offensive rebound rate edge, and does it hold against the expected rotation? |
| Step 3Check the possession count | 67.6 projected possessions | -0.3 versus the two teams’ 68.0-possession historical tempo midpoint. | Which team can keep the game near that lower projected count, and what stops transition opportunities? |
| Step 4Test roster sensitivity | 1.5-point movement toward UMass Lowell | Baseline +4.5 home · roster lens +3.1 home. | Which source-listed players account for that movement, and is there dated evidence for their current availability and role? |
Missing rows mean the exact supporting record did not pass the notebook’s identity or numeric checks; absence is not scored as a neutral signal.

Who carried the old possessions?
The three highest-minute contributors in the latest completed season. These rows preserve recorded production for preparation; they are not a projected rotation or an availability decision.
What should the staff test first?
These role signals come from the same completed-season player records. Each question is attached to a recorded workload or rate field; missing denominators remain unavailable.

These links join the historical workload table to the retained national coordinate archive by exact player and team ID. The questions use recorded attempt denominators to choose film; they do not predict a current rotation or treat an archived shot map as availability.

Who is listed today?
Exact-ID rows from the current roster snapshot, ordered by prior recorded minutes. Status is an observed listing label; it does not establish eligibility, availability, a commitment or a projected rotation.

Same-program, different-program and new-to-dataset are exact retained roster observations. Recorded prior minutes sum only valid attached stat profiles; they do not establish current availability, eligibility or role.
Where is prior experience attached?
Source positions group each current listing as guard, forward, center or unreported. Minutes belong to retained prior-season stat profiles and stay separated by same-program, different-program and other observation status. They are context for film review, not a projected rotation.

Variance belongs in the story.
The nominal home-margin range covers 31.9 points, so the forecast is a starting point for preparation rather than a script. Identify which lineup and shot-quality questions could move this game toward either edge.
Questions for the next check
- Which lineup combination gives the underdog its clearest path toward the top of the range?
- Can the projected favorite reproduce its best Four Factor possession against this opponent?
- Which current roster or availability source should be checked before publication?
Why the baseline leans.
| Factor | Home attack | Away defense | Away attack | Home defense | Edge |
|---|---|---|---|---|---|
| Shot quality | 51.6% | 52.1% | 51.5% | 53.5% | Home 1.5 pts |
| Ball security | 17.4% | 15.0% | 18.4% | 17.9% | Away 1.8 pts |
| Second chances | 26.5% | 30.4% | 30.5% | 29.5% | Away 5.0 pts |

Checking the current forecast edition and its qualifying market observations…
Keep the evidence chain open.
- Confirm current availability and the expected rotation from a dated update.
- Use the roster and player archives to identify the personnel behind each factor.
- Read the interval before treating a close projection as a decisive edge.
Follow the record.
The schedule ID, model edition and captured forecast remain attached to this notebook. A missing market observation is unavailable evidence, not a zero.
