Terms Glossary
Fields Gained: A ball progression metric that simply measures how far the ball is advanced relative to how far you are from goal. If you start 60 yards from center of goal and the move ends 40 yards from goal you just gained 0.33 Fields (20/60).
Efficiency of Ball Progression: Fields Gained per Ball Loss. Simply total fields gained divided by times you lost the ball (failed passes, dispossessions, offsides, take-ons failed)
Buildups: actions taken in the buildup to a shot or a dangerous touch (successful open play control within 20 yards of center of goal) with weight given more for shots and closer shots. More weight given for intentional actions (passes, take-ons) and less for ball recoveries, aerials, ball touches, etc.
Attack Maps: Volume of fields gained per minute (progressing and receiving) is the size of the players dot with production per minute the color. Production is a scale with efficiency of ball progression weighted the most at the back and shots and buildups weighted the most up top.
Deep Completions: Simply passes and take-ons completed within 35 yards of goal. Closer than 15 yards get heavy weighting with those outside 25 yards getting very light weighting.
Shooting: Just a basic xG model. Capping shot quality so a single .8 chance doesn’t tilt things and not scaled to goals for two reasons: 1 it’s hard and I’d rather spend time elsewhere as you can find that anywhere, mine won’t be as good as Caley or FotMob, and 2: to not bias the mind with what the score “should” have been.
Shot Quality: self-explanatory, basically how close the shots are
Shot Per Deep Completion: how often teams are converting their deep touches into shots
High Takeaway Rate: How often the team wins the ball back within 45 yards of opponents goal relative to how often opponents pass in that area.
Long Possession Share: percent of touches coming deep into settled possession
Defensive Action Rate: how often a team attempts defensive moves (tackles, interceptions, challenges, blocks) per opponent touch
Dead Ball Production: shot production coming from dead ball situations, not just direct kicks but also several actions afterwards
DZ%: percentage of open play completions coming in the Danger Zone.
Transition Opportunities: if a team starts 60+ yards from goal and moves into a dangerous position or gets a shot off within 15 seconds.
Transition Production: shooting production on transition opportunities
Central Touch%: % of offensive open play touches in the central third of the pitch
Cross Rate: % of open play final third passes that are crosses
Block Rate: % of opponents shots which are blocked by outfield players
Passing Verticality: average fields gained attempted (.07 is average pass goes 7% of the way towards goal)…goal kicks excluded.
Player maps show the rank of the player for the week in efficiency and buildup. Buildup looks at how many buildup actions you’d expect for a player getting their touches and compares how many they actually made.
