They can attempt a field goal regardless of whether it's a two-pointer or a three-pointer , they can end up on the foul line or they can turn the ball over. However, simply summing those three results does not provide the number of possessions because shooters can attempt either one, two or three free throws on any given possession. Box scores don't explain how many shots a player was fouled on, so we have no idea of knowing which fouls resulted in and-ones for example without looking through historical play-by-play data.
Just trust on this one I've read the studies and they're too complicated to explain in a short space and accept the fact that the 0. So now that we've got that out of the way, all this stat really does is calculate the number of turnovers a player will make in individual plays. Turnovers and turnovers per game are both dependent once more on pace of play and the amount of time a player spends on the court.
This rate statistic eliminates those detriments and focuses solely on the percentage of times a player turns the ball over compared to the amount of times they're involved in the play. Turnover percentage still can't factor in the passes that a player makes that result in non-turnovers i. Therefore, it's still a fairly limited stat because it only focuses on the true outcomes of possessions when that player is involved. That's one area of his game that he really needs to work on.
Whenever a shot clanks off the rim, there are four possible outcomes: The ball could go out of bounds and be counted as a defensive team rebound; the ball could bounce of a defensive player and go out of bounds to be counted as an offensive team rebound; the ball could be pulled down by a defensive player and be counted as a defensive rebound; or the ball could be pulled down by an offensive player and be counted as an offensive rebound.
If you add up all four of those results, you account for all of the potential rebounds in a game. Offensive rebound percentage calculates the percentage of available offensive rebounds that a player grabs while he's on the court. This is the last of the commonly-used offensive tempo-free rate stats and much like the previous two, it doesn't account for pace or volume.
Once more, it's too much trouble to go back and retroactively look at all historical box scores. No one really wants to do that. How I interpret that sentence: The big man for the Sacramento Kings grabs the offensive board nearly a fifth of the time that his team misses shots which happens quite a bit. Seeing as three-pointers are worth three points and two-pointers are worth two points, this makes sense.
Don't make the mistake of thinking that the multiplier in front of three-pointers should be 1. Essentially, it is in the above formula because three-pointers are counted one time in field goals and another 0. So, as for the merits of effective field-goal percentage, tell me which of the following players you'd rather have:.
Player A attempts 10 shots from the field, all from within the three-point arc, and drills five of them. Player B attempts 10 shots from the field, all from outside the three-point arc, and drills five of them. In short, the formula below takes 12 different stats available for any specific player.
Those stats are weighted differently field goals made will be worth more than a defensive rebound, for example. In simpler terms, PER scores include basic statistics like field goals made, steals, three-pointers made, and then subtract things like free throws missed, turnovers, and fouls. Hollinger has clearly given more weight to the categories that he feels are more important and less weight to the stats that are slightly less of a factor. His numbers are widely considered to be the most accurate, and his formula has become the league-wide standard used to calculate PER.
The good news is that you never actually have to do any calculations yourself. The formula listed above is a simplified version that uses linear weights. First, PER is a metric just like any other mathematical model. For example, does a block in the first quarter have the same value as that key block in the third quarter that sparked the momentum change and the comeback?

I found the weight of a stat by adding one of that stat to the player's season totals but not to the team or league , and finding the affect of that addition on the PER. I was shocked to find that the PER—before adjusting it to make the league average equal The column showing "Weight" is actual weight multiplied by 1, explained below , and the "Approx. So, what's up with the 1,? That is the approximate adjustment used to set the weighting of the league average of above stats equal to the league average PER.
In other words, using those weights to any one player will recreate his PER before you set the league average PER to We're almost there.
