I spent a lot of time thinking about ID and SB connection and I don't know if the lack of ID is a problem if you could block your opponent. Also if ID is not enought to avoid a shot, how the same level of SB could block it?

Preventing a shot and blocking it are to different things. ID works against a couple of skills, the actual shooting position, the tactic etc. There are a lot of points which influence your player before he decides to take a shot. But SB will only work against the actual shot.

Then our defender try to block that shot and if we have a similar level of SB we'll probably see the same % of shots blocked (because the same level of IS goes against the same level of SB) but more points against. Here a stupid example: 1 block every 4 attempts (=25%) and 6 pt but 2 blocks every 8 attempts (=25% again) and 12pt. And personal fouls could increase too (= more free throw attempts). Not good at all, but I don't think that with ID=x-1 the opponent is going to take 4 more attempts.

You are missing a very important point here. SB alters shots. Your player could finish a game with 0 blks, but hold his opponent to 0-10 shots. The number of blocked shots isn't that important, it's the defensive benifit which counts. I have two bigs with a shot blocking ratio of 35%.
The first one has 5% shooting foul, 30% altered shots and 30% failed actions --> the opponent scored.
The second one has 0% shooting fouls, 53% altered shots and only 12% failed actions. You see, they have the same % of blocked shots but different impacts on my defense.

Now with ID=x-1 I have more space (both wage and potential) to give him 2 more level of SB and I have a player that will tend to block more shots. In the example he needs to produce 3 more blocks but I say I overrate the plus of shots.
With more SB our defender will be capable to block more shots and will commit less fouls even if his opponent try to face him more times. Again, he will tend to block but if he is capable to do that he will have more success and commits less fouls.

With less ID your player could end up defending less shots. He will be to slow/weak to defend his opponent which could result in open shots. It's true that your guy could block more shots if you give him +2 SB with -1 ID. But I would prefer a big which defends 15 shot attempts/game rather than one which only defends 10 shot/attempts/game.

Yeah in my post i didn't clarify this, but we agree that by successful individual shot defense, we all mean the opponent missing on a guarded shot, be it a block, an altered shot>miss or a straightforward guarded shot>miss (I'm not totally convinced that ID has no impact at all on this last case, it might be something like the impact of SB on the team ID rating, but I'm happy to go with Nachtmahr indications on this).

This is the trade-off that would be interesting to measure at a given level of OD vs Flow. Then if we have a rough idea of how much an extra point in ID increases the successful defense (by reducing the unguarded shot overall number) and how much SB does the same (by reducing the FG% on guarded shots), we could have a much better idea of what builds are preferable. Granted, SB also gives a small contribution to reducing the number of unguarded shots too, trains probably faster, it's cheaper in the salary formula and it should become increasingly beneficial at higher OD levels.

One thing I noted is that even when OD is much higher than PA (like tremendous vs proficient in the B3) you still have high numbers of assists (like 20+). This could be explained with the fact that the open shots are less overall (compared to a prominent vs strong), but players hit them at a higher clip. It is slightly puzzling, though.

Yeah OD and ID are the "first step" about defense. Without them... you see Lakers defense? :D
I don't want kill ID but I like to find a good compromise between ID and SB.

In fact my thought started after the decision to try the shot (OD+ID+Stamina have already worked), in particular a shot in the paint, and after that the opponent flow, contrasted by my OD, carry the ball into shooter's hands. This one doesn't pass the ball and believe that he has good chances to make 2 points. Here comes SB. Maybe SB is counted into the Inside Defense Ratings but it's another story.

As you say, if ID is high that shot (if taken) will be guarded or it will be a very difficult shot to do. If ID is not enought we'll see an open shot. SB is more useful with guarded shot because to block an open shot we need someone like Dhalsim!

With an X level of ID (helped by OD + Stamina) my defender allows 15 attempt for example and taking the Nachtmahr's data he will block or alter (same results=no points) 2/3 of the attempts. For 5 times the opponent will make point and/or will go to the line.
With the same opponent's IS and the same defender's SB but with less ID (helped by the same OD + Stamina) we'll see more attempts. I swear, I talk only 1 level less. Maybe my defender will fight against not 15 but 18 (21?) FGA. And he will blocks/alters always 2/3 of them: now the opponent will find the rim 6 (7?) times.
What I say is that 2 more levels of SB probably will work better and block/alter that 1 (2?) other shot(s).

Why this suicide?
Because the opponent team will give more attempt to that man (as I say above a sort of iso) taking away the same number of attempts from other guys. And I do this because my defender, that has more SB, know what he has to do. Like a trap!

Preventing with ID. Work on the shot with SB . I tattoo this on my arm :D

Yeah, my bad. SB not only blocks the shots but works to limit the damage.
Using your data (your first big) we can say that if the opponent takes 20 FGA he will go 6 times to the rim and 1 time to the for two FT. With more ID the opponent will have less FGA. Is this ok?

I agree that with less ID my player will prevents less shot. And this is the point: more FTA for the opponent (and less for his teammates) but more power to blocks or alters those "bonus" shots.
Maybe what I've not understand is why he will give more open shots (=easy points).

With less ID your player could end up defending less shots. He will be to slow/weak to defend his opponent which could result in open shots. It's true that your guy could block more shots if you give him +2 SB with -1 ID. But I would prefer a big which defends 15 shot attempts/game rather than one which only defends 10 shot/attempts/game.

Yeah mate! This is the focal point of my idea. In the same match does it work better a 15/15 ID/SB or a 14/17?

With more ID the opponent will have less FGA. Is this ok?

With Nachtmahr and Trainerman explanations I believe that the open shot FG% depends on the shooting ability of the player and the defensive "team rating". Apparently if you have a C with 15 IS taking an open inside shot, he will score at a much higher percentage if he's facing an ID "team defense" of 10 rather than an ID "team defense" of 6. How much more I don't know, but individual ID on big men is the main contributor to this inside "team defence" (which is described in the team ratings in the boxscore), SB contibutes too, but much less.

So on top of keeping the opponent away from their paint and preventing open shots, ID should also reduce the open shot FG% when that is not successful.

Further, if theoretically you have 2 big men with 20 ID and 4 SB, you would not be in an ideal situation. Your high team ID rating will be extremely high, so the percentage of open inside shots faced will be low, but you won't have the SB to be successful in guarding those shots.

If conversely you have 7 ID and 20 SB, you also won't be in a great situation: lots of open shots where your monster SB won't help.

I can see why Nachtmahr is saying he likes to keep it close. Without being able to quantify the effects it's impossible to say whether 17-17 is better than 16-18 or 18-16. We know that SB is faster and cheaper to build though, so even if 18-16 was more efficient ultimately you might be better off with 17-17 from a training perspective.

In order to assess all this we'd need data to run regressions on the various skills, so that we can estimate how much they contribute to the ratings and to the statistics (meaningful statistics such as open shots FG%, guarded shot FG%). Something like this (for ratings) must have been done for the coefficients included in Coach Parrot. It requires large amounts of data, especially because in our case it would be best if both the offensive player stats and the defensive player stats (at least the differentials plus the team ratings which are always available) in the sample were known.

So in general OD and ID are most important for shot selection and what works out to be open shots, but I wouldn'T say SB is a complete non-factor.

That's what Nachtmahr said too, quoting BB-Charles. We all agree that SB also influences shot selection although not nearly as much as ID.

So guys, I show you something which is exactly what we discuss here: team defense (OD/ID), the amount of defended shots and SB.
For the last five seasons I played with a strong OD (OD 14-17) line up on PG, SG and SF. And as a C I had Sutherland.

season 24: Sutherland defended 11.9 shots/game
season 25: Sutherland defended 14.8 shots/game
season 26: Sutherland defended 12.7 shots/game (here I played with a OD 11 SF for the whole season)
season 27: Sutherland defended 14 shots/game
season 28: Sutherland defended 15.3 shots/game (wih 136 blks in 25 games, nr. 1 in BB)

and now this season after I sold my OD guys and have only one of them left.
season 29: Sutherland defends 10.1 shots/game

He's playing the same minutes, has almost the same blocking rate (30-35%) and shooting foul rate (6-10%). My opponents are the same. So there was no big change.
But because of the lack of OD on two of my first three positions there are more open shots for my opponents. They can exploit my current OD weakness and pass the ball to open players. During season 24-28 I hold my opponents to 10-12 assists per game. This season it's up to 15. That's a raise of 20-50%.
And here we are back again at the starting point. You have to balance your team. I have one of the best in-the-paint defenders but I can't use him effectively because of his teammates. And it wouldn't help me if Sutherland has ID 20 and SB 20. One guy can't control the whole defense...

You are missing a very important point here. SB alters shots. Your player could finish a game with 0 blks, but hold his opponent to 0-10 shots. The number of blocked shots isn't that important, it's the defensive benifit which counts. I have two bigs with a shot blocking ratio of 35%.

The second one has 0% shooting fouls, 53% altered shots and only 12% failed actions. You see, they have the same % of blocked shots but different impacts on my defense.

In this example, are the procentages of all cases where the particular player has tried to defend a shot (can be seen in the play-by-play as "somebody shoots...with your player defending closely" or other comment of that sort)? And then simply judging by the result like this: scored-->failed action, miss with no block--> altered shot, miss with block-->blocked, foul-->shooting foul. Or did I get it all wrong?

Yes.

Also correct.

I have an excel sheet were I have just to insert the amount of defended shots, missed shots, shooting fouls and blocks. And than I get the percentages and all kind of other numbers like starting 5 defense etc.
