Four Factors

Effective field goal percentage is like regular field goal percentage except that it gives 50% more credit for made three-point

eFG% = (.5*3FGM + FGM) / FGA

**Turnover
percentage** is a pace-independent measure of ball security.

TO% =
TO / Possessions

**Offensive
rebounding percentage** is a measure of the possible rebounds
that are
gathered by the offense.

OR% =
OR / (OR + DR_{opp})

Dropp=Defensive rebounds from your opponent.

**Free
throw
rate** captures a teams ability to get to the free throw line.

- The formula describes the number of

turnovers.
Pts/(FGx*.693 + FTx/2*.693 + to).

(The higher number, on offense, means the more productive a team is.)

**Coach
MPG Diff**-
A stat that I’ve created that shows the total difference of a
players actual
minutes played and a their “projected” amount of minutes
played. I created it
to see if a coach was using his players wisely based on their overall
on court
performance. The lower the number the better off a team will be in my
opinion.
The higher the number means a coach is playing unproductive players
more
minutes than they deserve. Players that are long term injured and are
still on
the list will skew the results some.

All the stat headings are self explanatory. The last column EST/MPG is a suggested minute per game average that I’ve created based on a players on court production.

**Usage**

((FGA + 0.475 * FTA + TOV) * (Tm MP / 5)) / (MP * (Tm FGA + 0.475 * Tm FTA + Tm TOV))

Effective field goal percentage is like regular field goal percentage except that it gives 50% more credit for made three-point

eFG%
= (.5*3FGM
+ FGM) / FGA

**-True shooting %**

Higher ranking is better

Used for players or teams, true shooting percentage describes a team’s field goal, three point, and free throw shooting. How well does a team shoot when taking free throw shooting and three-point shooting into account? The formula is a ratio of points scored per total field goal attempts and free throw attempts, thus accounting for the additional points scored on three pointers. TS% = Pts/(2*(FGA + (.475*FTA)))

**Offensive
rebounding percentage** is a measure of the possible rebounds
that are
gathered by the offense.

OR% =
OR / (OR + DR_{opp})

Dropp=Defensive rebounds from your opponent.

**Free
throw
rate** captures a teams ability to get to the free throw line.

FTRate - FTA / FGA

**Assist
Percentage**
- the formula is 100 * AST / (((MP / (Tm MP / 5)) * Tm FG) - FG). It is an estimate of the percentage of teammate
field goals a player assisted while he was on the floor.

**-Turnover Percentage**

Lower
ranking is
better

How often does a possession end with a turnover? The formula describes the number of turnovers per possession for a team or player.

(Note: this number is actually different for players and teams -- for teams it's an estimate of possessions so you subtract offensive rebounds because those technically extend one possession. For players, you can look at that or the percentage per 100 plays => 100 * TOV / (FGA + 0.475* FTA + TOV).)

**-Pure point rating**

Higher ranking is better

Used mostly for point guards, pure point rating can be used as a proxy for point guard quality by approximating the rate at which a player creates scoring opportunities for others. How well does a player balance the benefit of creating an assist with the cost of creating a turnover? The formula describes the net value of scoring opportunities a player created for teammates per minute played. 100*((ast*2/3)-to)/mins

**Block
Percentage **(%Blocks):
This is the percentage of opponents’ two-point shots that are
blocked by the
player while he is on the court. It is computed by Blocks/(%Min *
Opponents’
two-point attempts).

**Steal Percentage** (%Stls): This is the percentage of possessions
that a
player records a steal shile he is on the court. It is computed by
Steals/(%Min
* Team Possessions).

**-Estimated touches per game**

Touches estimate the number of times a player touched the ball in an attacking position on the floor. The theory behind the formula is that once a player gets the ball, he can only do one of four things (aside from dribbling, of course): pass, shoot, draw a foul, or commit a turnover.

Touches=Field
Goal
Attempts + Turnovers + (Free Throw Attempts / (Team's Free Throw
Attempts/Opponents Personal Fouls)) + (Assists/0.17)

**-Percent of touches that have ended in shots.**

%Shoot = 100 * FGA / Touches. The percentage of a player's touches that ended with him taking a shot and not being fouled in the act.

**-Percent of touches that have ended in
passes.**

%Pass = 100 * (AST / 0.17) / Touches. The percentage of a player's touches that ended with him passing to a teammate in an attacking position on the floor.

**-Percent of touches that have ended in
turnovers.**

%TO = 100 * Turnovers / Touches. The percentage of a player's touches that ended with him turning the ball over.

**-Did player "Qualify" for post season awards**

**-Shots per game.**

The average number of shots a player shoots each game.

**Rating Systems**

**-EFF= Efficiency Rating from WNBA.com.**

Higher
ranking is
better

(((Points + Rebounds + Assists + Steals + Blocks) - ((Field Goals Att. - Field Goals Made) + (Free Throws Att. - Free Throws Made) + Turnovers))

**-Defensive Value**

Higher ranking is better

Defensive value: Used to approximate a player’s defensive value to her team based upon blocks, defensive rebounds, steals, and personal fouls. How valuable is a player to her team defensively? The formula describes the value of a player’s defensive contributions per 40 minutes. ((dreb * .511 + stls * 1.60 + blks * .98 + pf * -.22)/minutes) * 40.

**-Points per empty possession(Pts/zpt)**

Higher ranking is better

How
often is a player
individually responsible for the added value of scoring possessions and
the
cost of non-scoring possessions? The formula describes the number of
points a
player scores per missed field goals, missed free throws, and
turnovers.
Pts/(FGx*.693 + FTx/2*.693 + to).

**MEV/GM
**– **A rating
system based on the following
formula per game:**

MEV = pts - 1.032*fgx - 0.587*ftx + 1.193*as + 1.030*or + 0.512*dr + 1.603*st + 0.981*bk - 1.448*to - 0.225*pf

**PER**-
A
complicated player rating formula that is known mostly in NBA circles.
I’ve
used a linear stat version and I’ve adjusted it for the college
game.

**Player
Win Share**- The "estimated" amount of wins a player has helped his
team achieve.

**Offensive
Synergy **- The players EFG% + their Assist Rate

**Player
Value **–
A value that is team specific for each player. Meaning if that player
is out of
the line up the team overall rating will decrease by that players value.

**The formula is:**

**PxTS% = (tPTS-pPTS)/(2*((tFGAs-pFGAs)+0.44*(tFTAs-pFTAs))**

**Draft
Grade **–
A stat based NBA Draft Grade base off of my BEMR player rating, a
players, class,
height and potential NBA position. They are not my opinion! They are
stat based.

**BEMR**
– My own
player rating based on numerous statistics. Compared to other player
rating
systems I think I subtract slightly more for things that generally
won’t help
your team.
