NBA 2K19 Player Ratings Generator Tool

Postby Suns_Of_Thunder on Fri Sep 07, 2018 3:09 am

Roster creators! CAP users! Modders!

When editing rosters and players, have you ever wished there was something available that could make your job a million times easier, that could just take a few stats and crank out a number for every single attribute for a player? Obviously over the years there have been some great tools available, and most people who do this sort of stuff all the time at least loosely have some formulas they use, but it's been 7 years since I last saw a public tool that actually had thorough formulas for even almost every rating, and that was just some random guy's Google Doc that I'm fairly sure was never really meant to be public anyway (and was made expliclity private after just a couple of months).

So I decided to create one. And in doing so, I took the "almost" out of the sentence from earlier. And then made it even more complex than it needed to be. See, what I've done is made a Google Sheets document where all you have to do is find a few stats, and it runs those numbers through 725 different formulas I have made to generate accurate results for all 49 attributes (the one caveat being that I condensed durability down to one "overall durability" rating), 11 of the most important tendencies, and every single badge (and yes that even includes the personality ones).

So without further ado, I bring to you...

The NBA 2K19 Player Ratings Generator Tool


I am also attaching a link to a 20 minute video which acts both as a tutorial on how to use it correctly and a discussion on a few flaws I've found in testing it. Luckily, I've now fixed many of those flaws! Here is a list of things I've updated in the couple days since making the video:

  • Added minimums and maximums so that attribute ratings cannot be higher than 99 or lower than 25 and that tendency ratings cannot be higher than 100 or lower than 0
  • Proportionally lowered post ratings for non-post players
  • Slightly reworked the formulas for Off-Dribble Shot Mid-Range, Off-Dribble Shot Three, and Speed with Ball to not be so top heavy
  • Slightly lowered the maximum rating for Ball Control
  • Drastically changed the Driving Dunk formula
  • Fixed a bug in the rating system for Contact Dunk that was making the rating always generate as 27 and was nullifying the generation of the Posterizer badge
  • Connected Lateral Quickness and Acceleration with Speed so that if you want to override the generated Speed rating based on the eye test, it will affect related attributes
  • Same as above, but with Vertical and Driving Dunk, if you want to override the generated Driving Dunk rating based on the eye test, it will affect related attributes
  • Reformulated Reaction Time entirely, much more realistic
  • Fixed generation of the Putback King badge
  • Made High Work Ethic, Corner Specialist, Mid-Range Deadeye, Deep Range Deadeye, and Bruiser badges generate slightly more often
  • Changed formula for floor general to weight it more in favor of PGs
  • Reworked part of the standing dunk formula
  • Fixed standing layup bug that affected about 10% of players
  • Small change to the lower end of the shot three formula

All being said, I am extremely proud of the many hours of work I've put into this and believe this is as accurate as we can get right now to a universal tool for generating player ratings. I spent a long time making sure that the averages in the real world NBA correlate to the median in 2K of their respective ratings for every attribute, plus for each octant, max, and min, etc., so as to reflect the curve that 2K generally implements for each rating. BUT that doesn't mean this is perfect in every way. I'm not that arrogant, to think that I've somehow cracked 2K's code, especially considering they clearly don't and honestly can't accurately rate everything with a simple formula. So here is a few disclaimers:

  • This tool is designed to be most applicable to stats hosted by RealGM. You may wonder "why not Basketball-Reference"? The main reason for this is that I am aiming for this to be a universal tool that can be useful for all sorts of different leagues and time periods. Basketball-Reference's accuracy and depth is unmatched except by the NBA's official website, for the last 15 years of the NBA and the last 5 of the NCAA. Anything outside of that very limited list of things they don't have. I have found RealGM to have by far the best combination of depth and universality.
  • Due to the previous point, I would like to advise you that if you are creating a current/recent NBA roster and you already have a reliable formula using Basketball-Reference or NBA.com stats for: Post Fadeaway, Post Hook, Post Control, Open Shot Mid-Range, Standing Dunk, Shot IQ, Shot Contest, Low Post Defensive IQ, Boxout, Hustle, Pass Perception, or any of the tendencies I provide which are listed under the Jump Shooting or Post Play categories, you may be as accurate or potentially more accurate by sticking with your old formulas, especially the ratings listed that I bolded.
  • Many attributes affect other attributes/tendencies/badges, so if you use your own formula or simply decide something looks wrong, input it into its correct spot in the sheet so that it makes necessary adjustments to related attributes.
  • Athleticism-related (and to a lesser extent, mentality/iq-related) attributes cannot be calculated from statistics at nearly the same level of accuracy as skill-based attributes. I've done as well as I can to come up with good estimates, and I'm quite happy with most of the results I get for speed and strength, but definitely double-check these. Especially dunks, that's easily the most egregious stat on the list, even after a massive improvement I made with them a couple days ago.
  • I've narrowed durability down to one overall attribute. If you know a player has an injury history with a certain body part, lower it proportionally.
  • On-Ball/Pick and Roll/Low Post/Help Defense may be occasionally off, thanks to how limited statistical analysis of defense in basketball is. From the testing I've done with it, I've made sure it's quite accurate, but it won't always be perfect.
  • In NBA 2K games, intangibles literally does nothing aside from falsely raising and lowering overall ratings. No in-game effect, no sim effect. What I came up with is more designed toward the actual intangible factors of basketball, but I certainly wouldn't blame you if you instead just used it to fix overalls in the same way 2K does.
  • Potential's obviously not perfect, I can't see the future. It's more of a prediction of how 2K would judge a player's potential than my own analysis.
  • Not hugely happy with how the bottom end of the Postup Tendency turned out, especially since the vast majority of players will be in that range. Hopefully a quick fix soon.
  • Great post defenders generally seem to have their on-ball defense nerfed
  • Context is everything. For all of this, and honestly for life in general, but in particular for the badge generation section. Those are more of estimates than anything, especially in the personality section.
  • If you notice any trends in the ratings that are generated for you that maybe seem a bit off, don't be afraid to contact me, in this thread, via PM on this site, or by emailing me at sunsofthunderofficial@gmail.com
  • If you have any suggestions for tendencies you would like me to add formulas for at some point, please comment them on the thread here.


Hope this tool can help many of you, and happy roster editing!

Thanks man. I've been watching your vids for a while now and they've helped me finally make the decision to switch to PC and try to start getting into modding too. I'll really appreciate your opinion on this once you test this out!

You're welcome, glad you're planning on using it! If you find anything that seems off, contact me about it. In testing, I've only used it for keeping players within the same league so far, so I'm not sure yet if I may end up needing to tweak a couple things to make it more compatible with draft classes. Hopefully it works just as well as it does with rosters though. :)

No problem. It's something I've always been looking for while creating rosters but never found one that was quite extensive enough, so I decided to make one and hopefully it comes in handy for people.

Update: Replaced former badges 'Low Ego' and 'All-Time Great' with new badges 'Team Player' and 'Extremely Confident'. New formulas for them. Still working on trying to do something about on-ball defense for posts.

First update I've made to this in quite a while, mid-range shots should be nerfed a bit to be more realistic.

I think is to nerf ...
I work on 2002 roster
With the new formula Kobe have 40 and D-Fish 44 :shock: :shock: :shock:
The old formula was better i think

Can you send me the old version version of the player rating generator too finish my roster please ?

Thanks for your work

Yeah the midrange ratings are too low. I'm making a 91-92 roster for PS4 and Jordan had a mid range of 40 something can't remember exactly

Yeah you guys are right, the new formula's further off than the previous one. I've restored the rating to the one that's too high until I get a new formula that actually puts the stats where they should be figured out.

Although I do have to say I'm not getting them nearly as incorrect as you guys are, can one of you maybe send me an example of it turning out that badly for you, because for example I just tried 02 Kobe in my private version of it and got a 72 open mid (still too low but much closer than 40)

Done lots of work on this this week, hoping to release updates for about a dozen attributes tomorrow, including a mid range formula that should actually reflect real life

Re: NBA 2K19 Player Ratings Generator Tool

Postby Suns_Of_Thunder on Sun Oct 28, 2018 6:40 pm

The tool is now officially updated! Things I have changed in this update:

- Post Hook: This was way too high in the original formula. As very few players are good at it in real life or in 2K, this needed to be nerfed. Don't be shocked when guys get legit 25s here now.
- Shot Close: I've taken away (or at least massively limited) what I call the Greg Ostertag effect, where decently efficient but talentless big men are considerably overestimated by this formula
- Open Shot Mid-Range: Finally found a balance between the original formula being way too high across the board and the updated one being way too low. I believe I've discovered the problem that made some players show up on the forties that definitely don't deserve to and fixed it. Also rewards volume scorers now more.
- Shot IQ: Non-volume scorers were too low, aimed to fix that and to widen the bias in favor of high IQ and experienced players. Slight general increase.
- On-Ball Defense IQ: Was too high for too many guards. Have reworked the formula to make it fit closer along to what 2K's quadrants are. Guards/wings that are weak and short have been lowered, plus a bit more of a handicap for age.
- Lateral Quickness: Lowered across the board, particularly for guards. Players are penalized more harshly for excessive height/lankiness that makes lateral movement generally less fluid.
- Speed: Similar changes to the lateral quickness ones tbh
- Speed with Ball: Connected the rating more closely to the changes in speed and made ratings less of outliers compared to each other
- Acceleration: Noticeably lower, connected more closely to speed, much heavier penalty for age
- Vertical: HUGE increase, pretty much across the board
- Strength: Previously had been too far scaled by position. Still there, but a combination of that and an overall scale so that we don't constantly have Marcus Smart successfully backing down Rudy Gobert anymore.
- Stamina: A simple 10 point drop across the board to make it closer to 2K's scale

Other attributes indirectly affected by these changes: Standing Layup, Driving Layup, Post Fadeaway, Post Control, Contested Shot Mid-Range, Off Dribble Shot Mid-Range, Standing Dunk, Driving Dunk, Contact Dunk, Shot Contest, Low Post Defense IQ, Hustle, Pick & Roll Defense IQ, Potential, Shot Under Basket Tendency, Shot Close Tendency, Shot Mid-Range Tendency, Putback Tendency, Postup Tendency, 29 Different Badges.

Still watch out for athletic and defensive ratings being off. I have changed the provided example from 2017-18 Real Madrid Luka Doncic to 2017-18 Cleveland Lebron, and the most obvious problem right off the bat is he's listed as 46 on-ball defense. Yes, he's much worse at it than he used to be, but he's not that bad.

Thanks man. When you finish updating the Bulls can you send me the on ball defense rating for Jordan, Armstrong, Paxson, Hodges, Grant, and King? That way I can have a decent sample size to see what I might need to change in that formula.

Has there been any update for this? I've tried this and its a great way for me to fill in the blanks with ratings, tendencies, and badges for retro roster making like with atlplayboy23 is doing but there are some concerns I'd like to raise if this is still up for another update.
