Big Sky Update: Week 12
January 26, 2026Big Sky Teams Face Diverging Trends Heading into Week 12
The Big Sky conference enters its final weeks of regular season play, with teams exhibiting distinct trending patterns as observed through MACD indicators. This analysis delves into the top offensive and defensive trends for each team, providing insight into their momentum heading into the stretch.
Offensive Trends: Declines Emerge in Key Areas
Idaho’s Off Reb Pct has seen a significant decline, indicating challenges in securing second-chance opportunities on offense. Conversely, Northern Arizona’s shooting percentage has shown improvement, trending up strongly.
Defensive Trends: Strengths and Struggles
Eastern Washington and Idaho have both demonstrated improved defensive prowess, as evidenced by their opponents’ declining shooting percentages. However, Idaho State’s defensive turnover numbers have worsened, highlighting a potential vulnerability for the team. Northern Arizona’s defense has struggled in two key areas: its opponents’ shooting percentage has increased, while its Def Reb Pct has declined.
Taking Stock: Momentum Shifts Ahead
As teams navigate the final stretch of the regular season, these trends will undoubtedly play a significant role in determining their trajectories. The MACD indicator measures the magnitude of momentum changes, indicating whether a team’s trend is accelerating or decelerating. Idaho and Idaho State must regroup to address their rebounding woes, while Northern Arizona’s shooting surge may provide a much-needed boost.
Eastern Washington’s defensive improvement will be crucial in maintaining its momentum heading into the playoffs. Meanwhile, Idaho State’s turnover issues and Northern Arizona’s defensive struggles will require attention to overcome.

Looking Ahead
Big Sky Conference Recap: Week 12
As we analyze the Big Sky Conference for Week 12, several key trends have emerged in both offense and defense. By examining the Moving Average Convergence Divergence (MACD) indicators, which gauge momentum by comparing short-term and long-term moving averages of a team’s performance metrics, we can identify which teams are genuinely improving versus those riding unsustainable momentum.
Offensive Trends to Highlight
Rebound efficiency has been an issue for Idaho this season. Their Off-Rebound Percentage (ORB%), which measures the percentage of available rebounds secured by a team, is trending down at 0.235, compared to their season average of 0.268. This decline in rebounding efficiency is a significant factor contributing to Idaho’s struggles on the court.
Conversely, Northern Arizona’s shooting efficiency has improved significantly, with an overall Shooting Percentage (SP) of 0.511 for the season. This uptick in scoring ability has been a key factor in their recent success.
Meanwhile, Idaho State and Montana have also seen their rebounding efficiency worsen this season. Idaho State’s ORB% is trending down at 0.272, while Montana’s is at 0.232, both of which are below their respective season averages of 0.319 and 0.295.
Defensive Trends to Highlight
Eastern Washington’s defense has shown significant improvement, with an Opponent Shooting Efficiency (OSE) trend that is down compared to their season average of 0.566. This increased defensive efficiency has been a crucial factor in their recent success.
Idaho’s defensive performance has also seen an uptick, with their opponents’ shooting percentage trending down from their season average of 0.517. However, this improvement may be short-lived if not sustained by consistent defensive efforts.
In contrast, Northern Arizona’s defense has struggled this season, with an Opponent Shooting Efficiency trend that is up compared to their season average of 0.556. This decline in defensive performance has been a significant contributor to their recent struggles.
Additionally, Idaho State’s turnover rate has increased, with their opponents taking advantage of their mistake-prone play. Monitoring these key metrics will be essential for coaches and fans to make informed decisions about team performance and strategy as the season progresses.
Metrics Glossary
Four Factors (Dean Oliver’s framework for basketball success):
- eFG% (Effective Field Goal %): Field goal percentage adjusted for 3-pointers being worth more (FGM + 0.5×3PM) / FGA. Higher is better offensively, lower is better defensively.
- TOV% (Turnover Rate): Turnovers per 100 possessions. Lower is better offensively (taking care of the ball), higher is better defensively (forcing turnovers).
- OREB% / DREB% (Offensive/Defensive Rebound Rate): Percentage of available rebounds grabbed. Offensive rebounds create second-chance points; defensive rebounds end opponent possessions.
- FTR (Free Throw Rate): Free throws made per field goal attempt (FTM/FGA). Measures ability to get to the line AND convert. Higher is better offensively, lower is better defensively.
Other Metrics:
- Elo Rating: Chess-style rating system that updates based on game results and opponent strength. Higher Elo indicates stronger team.
- Efficiency Margin: Point differential per 100 possessions (Offensive Efficiency – Defensive Efficiency). Accounts for pace of play.
- MACD (Moving Average Convergence Divergence): Trend indicator comparing 12-game and 26-game exponential moving averages. Positive MACD = improving trend, Negative MACD = declining trend.
