Stats to Ratings Conversion, Part II: Offense
Sun Jun 08, 2003 10:28 am
Again these are just a suggestion of one way to create players, how realistic the outcome has as much to do with the person with the Gravis gamepad in his hand as it does the ratings of the players.
I'd like to note these formulas use per-minute rather than per-game, this makes the bench players for most teams usable.
Again using the examples of Michael Jordan from the 1988-89 season, and Karl Malone from 1996-97.
Field Goals: (field goal attempts-per-minute X 100) plus (field goal % X 50)
Jordan put up 1795 shots in 3255 minutes, hitting .538 percent. 1795 diveded by 3255 = .551, X 100 = 55. .538 X 50 = 27, + 55 = 82/91.
Malone put up 1571 shots in 2998 minutes, at .550. 1571 divided by 2998 = .524, X 100 = 52. .550 x 50 = 28, + 52 = 80/90.
Note: a 90 & 91 live rating IS top-o-the-line useing this formula, the only player i've made yet to top this is the 50 points-per-game Wilt Chamberlain. Considering I can score 60-70 points on .660 shooting with either of these players in a 48 minute super-star game, there is no need to raise this.
Alternative: On older versions of NBALive I used to add 10 to boost this value, as jumpers are automatic in 2003 I stopped doing that.
Three Point Shooting: (Percentage of shots that were taken outside the line X 100) plus (3-point percentage X 100).
Jordan put up 98 3s out of his overall 1795 shots, and hit .276 pecent. 98 divided by 1795 = .054, X 100 = 5. .276 X 100 = 28, + 5 = 33/66.
Malone put up 13 out of his overall 1571, and didn't hit a single one. 13 divided by 1571 = .008. As he didn't make any of his three attempts, I multiply by 1000 and use that as his rating. 8/54.
Notes: This formula favors production over pecentage, so certain players may seem gimped.
Inside Scoring: (shot attempts - three-point attempts per minute X 100) + (recalculated fg % X 50) +or- a bonus based on the fg % .440.
For Jordan we subtract his 98 3-point attempts from his 1795 overall attempts for 1697, then the 27 3s he made from his overall 966 connects for 939. 939 divided by 1697 = .553, 50 = 28. 1697 attempts divided by 3255 minutes = .521, X 100 = 52, 28 + 52 = 80. As he shot .08 over .440, we add 8 to the 80 we already have for a rating of 88/94.
For Karl 1571 - 13 = 1558, we recalculte his inside shooting % for .554, 50 = 28. 1558 shots divide by 2998 minutes = .519, X 100 = 52. 28 + 52 = 80, as he shot .079 over .440 we add 8 for 88/94.
Note: Inside Scoring is the domain of big men, so forwards and centers will be better at this than guards. I don't care how few shots he puts up, or anybodys oppinion of a player, if he shoots .680 he is a good inside shooter. Use the primacy and FG ratings to define how good of a scorer someone is.
Note2: If a player shot lower than .440 I would subtract that from the rating rather than add, this is supposed to favor the high percentage shooters after all.
Passing: The way I do this is so convoluted I can only explain by example.
First step, we subtract Jordan's 3.58 tunovers-per-game from his 8.02 assists for 4.44, X 10 = 44(remember that number), I thought 40 seemed to be a nice even number so we add that to the 44 we already have for 84. Jordan had 650 assists in 3255 minutes, which adds up to 9.59 assists-per-48 minutes, X 10 = 96. we average out the two numbers(96 + 88 = 184 divide by 2 = 92)for a rating of 92/96.
Karl had 4.49 assists-per game and 2.84 turnovers-per-game, for a difference of 1.65, add 10 for 17(remember this number), add another 40 and we have 57. He also had 368 assists in 2998 minutes, or 5.89 assists-per-48 minutes, X 10 = 59. the average of these numbers is the rating 58/79.
Note: I know this formula is crap, but it's the best I've come up with so far.
Note 2: It's assists-per-game minus turnovers-per-game, so you're usualy adding a negative number from 40 for the first number, don't worry about it big men are supposed to suck at ball handling.
Dribbling/Ball Handling: The raw passing rating + a number based on assists - turnovers.
That number I told you to remember, ya know that 44 for Jordan, we need to make that a single-digit number. So we add the first digit(4) to the second digit(4), add that to his passing rating(92) as a bonus for 96/98.
Karl's assists-per-game minus turnovers-per-game X 10 was 17, add 1 to 7 for a bonus of 8 and add it to his passing for 66/83.
Note: Any better ideas, please.
