How do you read the columns in each "Win Profile"?

If you are not familiar with the basic stats used on Bucks Diary, such as Win Score and Win Contribution, please first browse the quick statitstical FAQ.

After that, its simple.

"Win Score Pos Average"= the average Win Score calculated according to the number of minutes 82games.com says the player played at each of the 5 traditional NBA positions.

"Opp Win Score per position": This breaks down the "Win Score Above Average" achieved by player's opponents at each of the position's the player played. Its meant to tell you if the player had defensive success at one position and not another. FOR THIS STAT, NEGATIVE NUMBERS ARE GOOD, POSITIVE NUMBERS ARE BAD.

"Opp Win Score Overall": Takes the player's opponents Win Scores Above Average and gives you the cumulative Win Score Above Average. FOR THIS STAT, NEGATIVE NUMBERS ARE GOOD, POSITIVE NUMBERS ARE BAD.

"Defensive Half Wins": This takes the opposite of the player's opponents cumulative Win Score Above Average and uses the Win Score Wins Produced formula to translate that number into how many wins the player produced on the defensive end by reducing the "Win Production" effectiveness of his cumulative opponents. Since you have to play both ends of the floor, these "wins" are only given 1/2 value and thus refered to as "half wins".

"Defensive Win Contribution": Takes the opposite of the player's opponents "Opp Win Score Overall", ie the player's opponents Win Score Above Average, and multiplies it by: (the player's minutes played/the cumulative player minutes for the team). The cumulative player minutes, if a team played a regulation season without over time would equal 82 * 48 * 5 or 19680. That is rarely the actual season total since most teams play overtime minutes.

"Offensive Win Score Overall": This is the player's Win Score Above Average.

"Offensive Half Wins": This is the same as "Defensive Half Wins" except that you use the player's Offensive Win Score instead of his Opponent Counterpart's Offensive Win Score.

"Offensive Win Contribution": The same as "Defensive Win Contribution" except you use the player's Offensvie Win Score overall instead of his Opponent Counterpart's Win Score.

"Total Wins (Win Contribution)": Here you add the player's Defensive and Offensive Half Wins, and divide by 2, and you add the player's Defensive and Offensive Win Contributions and divide by 2. The former is meant to show exactly how many games the player won when you consider both his offense and his defense and the later is meant to show how positive or negative an impact the player had on making the team a winning team, compared with the impact you would get from a merely average player playing the same position and taking up the same amount of playing time, with the average player represented by (+0.000)
