Advanced statistics

These statistics are calculated from the "linear" ones: those stats that we read from the schedules or box scores, but more accurate for measuring certain aspects of the game.
As the different teams -according to its style- play at different paces, we can't use game averages for comparing them.

In order to get those comparisons, we must define the concept of possessions, which is the basis of these calculations. Basketball is a game where both teams alternate ball possession. Thus, the team that makes better use of its possessions wins.

We assume that a possession ends with a field goal, a turnover, or a free throw: the ball goes to the rival and possession ends.

What happens if a team misses a field goal but grabs the offensive rebound? Today, most basketball statisticians believe that a new possession to the team must not be scored, but the same possession continues.

Game Pace
It gives us an idea of ??the team's pace of play, expressed in number of possessions per game. We all know that there are teams who likes fast-pace games and teams that prefer slow pace. So game statistics are NOT useful to compare teams.

The formula is:

Pace = points/possessions*100

We calculate the possessions with the following formula:

Pos = FGA – OR + TO + (FTA*0.4)

Pos: possessions
FGA:field goal attempts
OR: ofensive rebounds
TO: turnovers
FTA: free throw attempts

Efficiency

We evaluate the offensive and defensive aspects and the differences between them.

Offensive Efficiency (off eff)
Usually we evaluate offensive points scored per game, which is somewhat awkward. If we think the game as a series of possessions, the team who scores more points in their possessions, will be the most effective. We must multiply this by 100 in order to express the points per 100 possessions, without considering to handle numbers with decimal places.

Offensive Efficiency = (points/possessions)*100

Defensive Efficiency (def eff)
As we measure offensive efficiency as points scored per 100 possessions, also we can measure the defense based on points received (or points from the opponent) per 100 possessions of the opposing team.

Defensive Efficiency = (received points/100 possessions of the opposing team)*100

Porcentaje efectivo de tiros de campo (eFG%) This statistic adjusts the field goal giving the extra value (one point) to the triples. This corrects the common FG% that underestimates the 3-pointer and long-range shooters, who misses more shoots than those who shoot closer to the hoop. For example: in Argentine LNB, 2009-2010 season, Juan Espil (a shooting guard) had 43.7 FG%. Adjusted, it means 57.8% eFG.

eFG% = (FGM + 0.5*3PM) / FGA

FGM: field goal made
3PM: 3 points made
FGA: field goal attempts

True Shooting (TS) o Lanzamientos reales
This category takes into account such field goals as free throws, in order to know how that player shoots globally. For example: For example: in Argentine LNB, 2009-2010 season, Martin Leiva (a center) was #8 in FG% with 58.72%. But, if we add the FTs, Leiva (a very bad free-throw shooter) drops to #91 with 54.8%.

TS = puntos / (2*(FGA+0.44*FTA)

FGA = field goal attempts
FTA = free throw attempts

Rebounds

Total team rebounds are of little value. Taking an offensive rebound requires different skills to take a defensive one, so it should be analyzed separately.

Taking into account the absolute number of rebounds given, or the average rebounds per game, it can lead to errors, since the 'available' boards depend on the effectiveness; if a team misses little, there are few rebounds to take. For example: Team A took 20 defensive rebounds in a game. If Team B missed 30 throws (meaning that there were 30 defensive rebounds in A's hoop) then A captured 66% of the rebounds in the hoop (20 of 30). But if B missed 25 shots, A took 80% of the rebounds (20 of 25).
The same for defensive rebounds (DR%, defensive rebound rate) and offensive (OR%, offensive rebound rate).

K
Offensive rebounds % = [OR/(OR+opp DR)]*100


OR = offensive rebounds
Opp DR = opponent defensive rebounds

Defensive rebounds % = [DR/(DR+opp OR)]*100

DR = defensive rebounds
Opp OR = opponent offensive rebounds

Assists and turnovers percentage
As with rebounds and other statistics, assists per game are not a good parameter, because it relies on the pace of play. More accurate is to calculate assists expressed in possessions who end in a turnover. Usually expressed as a percentage. Assists % = (assists/turnovers)*100

The same goes for turnovers. It's not the same to lose 10 balls in a game with 100 possessions, that one with 80. We prefer to calculate turnovers per 100 possessions. The ideal value depends on the pace of play, but we could say that the objective would be to lose less than 15% of TO and provoke the opponent losing more than 15% of the balls.

Turnovers % = (turnovers/possessions)*100

Free throws regarding field goals (FTM/FGA)
It is simply a way of expressing the number of times that a team goes to the line and how many times sent to the opponent to the line. This consideration (together with the effective field goal percentage, the offensive rebound rate and loss rate) one of the four factors that define the games.

Free throws per field goal = (free throws / field goal attempts) * 100

Expected wins

To win, obviously you have to score more points than the opponent. There is a calculation (tested in the NBA and college basketball) that according to points scored and received, we can estimate the number of games that would have won. Usually correlate well with reality.

Expected wins = offensive efficiency^14/(offensive efficiency^14+defensive efficiency^14)
