So lets for the time grant assuming they are going in platooned lineups. You could argue that their individual matchup who the have to outperform is likely to be of a lower standard. At a team level I don't see the logic for more than a marginal adjustment for the single specific player at a lower standard, no?

On playoff samples Stokes had effectively no sample too (1 game, after his initial head injury, before complications), whilst others might have less than huge samples in the windows in question. Olajuwon plays no more than a single opponent and no more than 4 games in the years in question and the years adjacent to the years in question. If one is big on playoffs conceptually it would seem to me hard to justify weighting these runs as a viable sample on which to assess a player.

Good point on Stokes, but with Hakeem we have a lot of playoff data from other seasons.

Hence there wasn't a claim that there wasn't. Just that it isn't there in the seasons chosen. I don't think it's impossible to thread the needle you're arguing just that it makes it awkward.

Playoff sample is important but player number 2 on the list has small unvaried sample in years chosen as peak and adjacent years. You could even take it to years adjacent to adjacent years and there's still only another two series though you would finally get to a 2nd round series (a pretty good offense, though hardly a powerhouse playoff team) and a series of over 4 games (2 total series in '87 none in '92). And this in an era (16 playoff teams of 23 for a couple of these years and then 25, 27 but the new teams still in expansion mode) and some of it in a decidedly lesser conference ('87, '88 at least).

It's not wrong per se ... it's just hard for me to square playoffs as any significant harm for Bol's case with accepting Olajuwon at two and doing so choosing years for Olajuwon with such small and unvaried playoff samples. Personally I wouldn't hold that against Olajuwon because it's something he can't control and I don't think players are that different in the playoffs (I think teams moreso can vulnerable to scheming) but then I wouldn't weight the playoffs that much. At the very margin I might note that unlike Robinson in his near 20 point on-off (19.9, 19.8, 16.8 per 48 minutes 94-96) years with his own weaker casts, Olajuwon at least isn't proving or clearly showing the level of impact that often gets you HCA and a better chance to advance and show a larger sample (though this is messier, two-way, is absence of clear evidence of very high impact rather than evidence of absence of huge impact and somewhat tangential).

When you can see Hakeem impacting the game at the highest level in different seasons, while acknowledging that he was even better in different seasons, I find it plasuable to assume that he would show us at very least similar defensive value in more favorable team situation.

You may disagree with my approach, but I don't think it's very controversial to use my way of deduction.

I'm not quite sure what all of this means regarding "impacting the game at the highest level in different seasons" (is this just "he was good in the playoffs") and I'm not that au fait with measures of playoff defensive impact.
Still as I read it ... that's not the ... not contradiction or "controversial" but not the sticking point that's awkward or at least it misses a chunk of it.

If lack of a playoff sample absence is any significant barrier to Bol. (And it seems it is for you though to what degree is unclear.)
and
You are rating a peak (and are choosing to do so and think different years are different enough to choose this as your voluntary, chosen approach)
then
It would seem likely that you would require significant playoff samples in these peaks.

You can choose not to ... justifying it based on other years ... but then if you care about playoffs much shouldn't you choose the other years (or operate over a wider span to allow greater playoff samples). Or if you trust small sample years ... well how much do you value playoffs. As before not impossible but it seems tricky to justify high playoff valuation and choosing small sample years. The transitive good other playoffs just becomes ... well either those playoffs mean that I should take the surety of these good playoffs or the playoffs mean less. And if the playoffs mean less ... that's fine (it's just can't much of a factor against Bol).

I'm repeating myself. I'd just struggling accepting threading this needle (as it appears to me) for myself without more on how (or how much each thing is a factor, what sort of process went into the ratings etc).

About Hakeem in the playoffs - again, we have seen him being great defensively in many series across his career and he was the best defensively in mentioned years. I don't look at the years chosen too rigidly, in the end Hakeem was the same person throughout his career, even with some changes in his game. He was absurdly good in 1993 playoffs and I don't see any reason why he wouldn't be able to replicate that 2 years before. I'm not talking about simple reasoning, but I also back it up with me tracking Hakeem's tendencies from various seasons. 1990 Hakeem didn't lack anything on defensive end compared to 1993 version, his footwork and ability to read the game was on the same level already. He was simply even more athletic and more active than ever.

Okay so part of it's playoffs less important than I was reading off you bringing it up. That does a lot of work. It's hard to calibrate what people are thinking off these snippets.

I tend to think of playoff performance (and especially stats and impact, more than underlying performance and ability levels) as fluky and heavily contextual. If you've done the scouting work and playoffs are lesser factor than I first inferred I can at least understand where you are coming from more.

On Olajuwon I would note by '93 the foul rate is down to safer levels where a conservative coach wouldn't frequently have (choose, you don't have to combat the prospect of losing a player by voluntarily losing a player - still there ultimately fouling out; for Hakeem 10 Dqs in '89, down to 6 in '90) to bench him, though '90 is also a down year i this stat (though it then bounces back up).

On Bol's minutes I would though refer back to previous posts. There's evidence of what I think is monster impact, such that even value rather than rate he warrants at least consideration. I can't see that two way players (say Zo or Cowens) even if they weren't offensive monsters, were demolishing offenses close to what he seemingly was rate wise.

Actually, Hakeem averaged the same amount of fouls per100 in 1990 and 1993 (4.8) and the two next seasons were only slightly higher.

I think your point is fair regarding Bol, I might consider him on my list. His defensive impact seems to be immense and eye-test certainly back it up.

I used fouls per minute rather than possession. I don't know which is a better measure of some notion of pure foul frequency ... but the game is set minutes not set possessions. If it's just a fluke of pace is slower ... it doesn't matter to a key point that he's in foul trouble less, though it would matter more broadly which measure is better.

By this he's fairly high rate fouler, still at 3.9 in '89 (slightly down on career average but if the career gradient to that point is down then it's gentle and inconsistent), down to 3.6 in '90 then back up to 3.9 in '91 then thereafter a consistent downward trajectory through to '97. His teams rightly kept him in game (and as I say playoffs are a small sample) but '89 and '90 playoffs he's on 5 fouls in over half his games. In the '93 run its 1 game. As I say samples, matchups etc. But it may be place where the player is a little different (and how he might be used may be different).

So ... sort of.
We don't have the full 97 on era lineup data.
We do have plus minus and therefore on-off for the 76ers from the late 70s. And Bol played a little for the 76ers.
We also have points for and points allowed when on (and so points for and allowed when off and in concert with minute totals a per [48] minute offensive and defensive on-off.

A search for something like jones cheeks erving realgm pollack fpliii (players, forum, the 76ers statistician, the poster who shared this) will find you the thread with more details. There are totals which mix years (suggests slight positive, but don't love this approach) but year to year the net flits from negative ('91: -6.1) to positive (92: 5.3) then back to a smaller negative (93: -1.9 in a smaller sample). Despite the net difference the two larger on sample years are both very strongly indicating he's enormously harmful to both offenses.
