A team's record against the spread — wins and losses covering, not outright. A team can be 10–2 straight up but 4–8 ATS. More relevant to betting than win-loss record alone.
When a team plays on consecutive nights with no rest day between games. One of the most reliable fragility flags in both sports.
The percentage of batted balls hit with optimal exit velocity and launch angle — the best predictor of hard contact and power output.
The percentage of all shot attempts directed toward the opponent's net. The best single measure of possession and territorial control.
Points allowed per 100 possessions. Lower is better. The best defensive teams hold opponents under 110. Elite defenses under 108.
Earned Run Average — the average runs a pitcher allows per nine innings. Under 3.00 is elite. Over 5.00 is a concern. One of the most important factors in MLB totals and run lines.
How hard the ball comes off the bat in mph. Higher exit velocity means better contact quality regardless of outcome.
An MLB bet that settles after five innings regardless of the final score. Useful when you trust the starting pitchers but not the bullpens. Removes late-game variance from the equation entirely.
The percentage of balls a batter hits at 95+ mph exit velocity. Measures consistent quality of contact.
Save rate on shots from the highest-quality scoring areas. Separates elite goaltenders from average ones.
How dramatically a team's performance changes depending on location. Some teams are elite at home and average on the road. Splits matter most in playoff situations and for teams with strong home crowds.
When a team intentionally limits a healthy player's minutes — usually late in the season. Check load management situations before any game involving star players. Undisclosed until close to tip-off.
Points scored minus points allowed per 100 possessions. The single best summary of a team's overall quality. Positive is good. Higher is better. More reliable than win-loss record over small samples.
Points scored per 100 possessions. Measures how efficiently a team scores, independent of pace. Useful for comparing teams that play at very different speeds.
How many possessions a team averages per game. High pace = more possessions, higher totals. Low pace = fewer possessions, tighter games. One of the most important factors in setting the game shape.
A formula combining completion percentage, yards per attempt, touchdowns, and interceptions into one efficiency number.
Hockey's point spread, usually set at −1.5 for the favorite, meaning they must win by 2 or more goals to cover.
Expected wins based on points scored versus points allowed — not actual results. Teams that significantly outperform their Pythagorean record tend to regress. More predictive than straight win-loss over small samples.
Baseball's version of the spread — almost always set at ±1.5 runs. The favorite must win by 2+. The underdog can lose by 1 and still cover. Changes the implied probability significantly.
The percentage of shots on goal a goaltender stops. League average is around .910 — anything above .920 is elite.
Scoring efficiency that accounts for three-pointers and free throws, not just field goals. More accurate than raw shooting percentage.
The difference between turnovers gained and lost. One of the strongest single-game predictors of NFL outcomes.
The percentage of team possessions a player is involved in while on the court. High usage = more shot attempts, more prop relevance. When a teammate is injured, usage rate often spikes — and props follow.
Walks plus Hits per Inning Pitched. Measures how many baserunners a pitcher allows. Under 1.10 is elite. Over 1.40 is a red flag. Lower is better.
