Overview

Trend Strength measures whether a player's analytical profile is improving, declining or remaining broadly stable.

Unlike the Overall Score, which describes the current level of performance, Trend Strength describes the direction and strength of movement.

Trend Strength does not measure player quality. A highly rated player can be declining, while a lower-rated player can be improving.

Where Trend Strength Is Used

Trend Strength is used by:

• Receiving Intelligence
• Rushing Intelligence
• Passing Intelligence

Each engine tracks movement in the categories relevant to that position.

Trend Strength is not part of:

• Historical Intelligence
• Dynasty Market

Historical Intelligence evaluates completed seasons. Dynasty Market has its own separate market-momentum system.

Two Levels of Trend Analysis

Category Trend Strength

Each analytical category receives its own Trend Strength.

This shows which parts of the player's profile are improving or declining.

For example, a player may have:

• improving Role;
• stable Efficiency;
• declining Production.

These category-level movements explain what is changing beneath the Overall Score.

Overall Trend Index

The Overall Trend Index, or OTI, summarizes the direction of the player's complete analytical profile.

It combines the available category trends into one overall directional indicator.

OTI should always be interpreted alongside the category trends, because a single number cannot show which areas are driving the movement.

The Three Trend Horizons

Momentum

Momentum captures the most recent change in the player's profile.

It is the most responsive component and helps identify changes that may have only recently begun.

Momentum answers:

Because it focuses on a short period, Momentum can move more quickly than the broader trend indicators.

L5 Trend

L5 Trend evaluates the direction across the player's latest five games played.

It provides an intermediate perspective that is less sensitive to one isolated performance than Momentum.

L5 Trend is especially useful for identifying:

• sustained role changes;
• growing or declining opportunity;
• improving or weakening efficiency;
• recent shifts in production.

The latest five played games are used, not simply the previous five NFL calendar weeks.

Season Trend

Season Trend measures the broader direction across all of the player's games played during the current season.

It provides the most stable view of whether the player's profile has generally strengthened or weakened over time.

Season Trend responds more slowly than Momentum because it includes a larger portion of the season.

Why Multiple Horizons Are Used

No single trend window can fully describe player movement.

Momentum is responsive, but it can be influenced by recent variation.

Season Trend is stable, but it can react slowly when a player's situation changes.

L5 Trend sits between those perspectives.

Using all three allows NFL Fantasy Mate to balance:

• responsiveness;
• stability;
• short-term change;
• broader seasonal direction.

This is why OTI may differ from Momentum or from the most recent category arrows.

Played Games, Bye Weeks and Absences

Trend analysis follows the player's sequence of games played.

Bye weeks and missed games are not inserted as zero-value performances.

For example, if a player appears in Weeks 5, 6 and 8 but misses Week 7, the trend sequence moves directly from Week 6 to Week 8.

This prevents:

• bye weeks from creating artificial declines;
• missed games from being interpreted as poor performances;
• calendar gaps from distorting the direction of the trend.

An absence may still be shown elsewhere as contextual information, but it is not treated as a zero-performance game within Trend Strength.

Evidence

Evidence indicates how much observed data supports a trend.

A movement based on only a small number of games receives less confidence than one supported by a longer sequence of observations.

Higher Evidence means:

• more data supports the direction;
• the trend is less dependent on one isolated performance;
• greater confidence can be placed in the displayed movement.

Lower Evidence means:

• the trend is still developing;
• the direction may change quickly;
• the result should be interpreted cautiously.

Evidence does not describe how good the player is. It describes how strongly the available data supports the trend.

Why Strong Movement Can Be Reduced

A player may show a large recent change but only a moderate Trend Strength when the supporting Evidence is limited.

This is intentional.

NFL Fantasy Mate reduces the influence of movements that are not yet supported by enough observations.

As additional games are played, the same continuing movement may receive a stronger trend value because the direction is supported by more evidence.

How Directional Strength Is Interpreted

• Strong positive values indicate clear, well-supported improvement.
• Moderate positive values indicate an improving profile.
• Values near the middle indicate stability, mixed movement or limited directional evidence.
• Moderate negative values indicate a declining profile.
• Strong negative values indicate clear, well-supported regression.

A value near zero does not always mean that nothing has changed.

It may also indicate that:

• positive and negative category movements offset one another;
• the movement is too small to be considered meaningful;
• insufficient evidence is available;
• the short-term and long-term horizons disagree.

Why the Current Maximum May Not Be +100

The current table is not forced to contain a +100 or -100.

Trend movement is evaluated against a reference built from movements already observed before the selected week.

Therefore, the strongest current player may receive, for example, +66 if his movement is strong but still below the most exceptional comparable movements previously observed.

A value of +100 or -100 means that the current movement reaches or exceeds the established reference for an exceptionally strong rise or decline.

It does not simply mean “best player in the current table.”

This allows Trend Strength to preserve historical context rather than assigning +100 to somebody every week regardless of how significant the movement actually is.

Why Momentum May Differ from L5 and Season

The three trend horizons can legitimately disagree.

For example:

• Momentum may be positive because the player's latest game was strong.
• L5 may remain stable because the broader recent window has changed little.
• Season Trend may be negative because the player's overall profile has declined across the year.

This is not a contradiction.

Each component describes movement over a different period.

OTI combines those perspectives into a broader summary, while the individual components allow users to see how the trend is developing.

Trend Strength vs Overall Score

Overall Score measures current performance level.

Trend Strength measures movement.

A player can therefore have:

• a high Overall Score and negative Trend Strength;
• a low Overall Score and positive Trend Strength;
• strong values in both;
• weak values in both.

For example, an elite player may remain one of the strongest at his position while declining from an even higher previous level.

A developing player may still rank modestly while showing clear improvement.

Trend Strength vs Baseline

Baseline compares the current profile with the player's previous completed season.

Trend Strength measures the direction of movement within the current season.

A player may be:

• improving but still below Baseline;
• declining but still above Baseline;
• improving and above Baseline;
• declining and below Baseline.

Trend Strength explains where the profile is moving. Baseline explains where it stands relative to last season.

Trend Strength vs Weekly Changes

Trend Strength measures the magnitude and direction of movement.

Weekly Changes translate meaningful recent category movement into simpler descriptive labels.

In practical terms:

• Trend Strength provides the underlying directional measurement.
• Weekly Changes identify which recent developments are important enough to highlight.

The two outputs complement one another.

When Trend Strength Is Unavailable

A trend component may be unavailable when too few played games exist to support it.

For example, early in the season:

• Momentum may not yet be available;
• L5 may not have a complete recent window;
• Season Trend may have limited Evidence.

When one component is unavailable, NFL Fantasy Mate relies on the trend information that is currently supported.

An unavailable trend should not be interpreted as zero, stability or poor performance.

How to Use Trend Strength

1. Review the Overall Score to understand current performance.
2. Review OTI to understand the broad direction of the profile.
3. Examine category Trend Strength to identify what is driving the movement.
4. Compare Momentum, L5 and Season to determine whether the change is recent or established.
5. Review Evidence before placing strong confidence in the result.
6. Use Weekly Changes for a concise summary of the most meaningful recent developments.
7. Add Baseline, Projection and Team Context for wider context.

What Trend Strength Is Not

Trend Strength is not:

• a player ranking;
• a measure of absolute quality;
• a guarantee that the direction will continue;
• a season projection;
• a dynasty valuation;
• a reaction to one isolated play.

Its purpose is to describe how the player's analytical profile is moving based on the evidence currently available.
