  • No no no, not THAT "Eric M Van".
There's probably a thread for this but the Fab Melo conversation on the front page has called into question Ainge's draft performance as a GM since taking over the Celtics. There's been the usual numbers analysis and gut feel posts and it caused me to wonder if there was actually a metric for how he and other GM's have performed draft-wise over the past 10 years or so.

There's some interesting stuff out there and I'd like to list some of it here because it's gotten buried among the threads and I think it's of value to have some historical context instead of the usual "He Sucks" Vs "No he don't" rhetoric.

As always, YMMV when these type of analysis are done, but that's half the fun of the debate.

I first ran into this link when looking for a site that rated GM's by their drafting acumen. *

http://www.cbssports.com/nba/draft/gm-ratings.
It misses the Sullinger/Melo draft and also this years (I don’t see the results of either of those drafts altering the “score” so much but the rubric is there if you want to work it out for yourself). It's obviously a bit dated and I'm not exactly on board with the analysis (apples to oranges in some cases), but it's a starting point and the explanation for the scoring is there so one could carry it forward.

Of much more interest to me is the analysis done by a guy at http://www.statdance.com/

The gentleman who did this used a lot of material from 82games.com which is pretty well respected by many in this community. It's a bit long, a bit involved, but worth the reading time IMHO and since I'm biased all ready towards Ainge and the Celtics, self satisfying.  :-*

This was done last year and again the rubric is explained, but this time in detail and it's pretty thorough and, I think, well thought out. It's in 4 parts

Some "findings"

Ranking The Best Drafting Teams

So, to summarize the last two sections: 3 teams drafted poorly with winning records, and 5 teams drafted well and had losing records. That means 23 teams either posted winning records with positive draft results, or posted losing records with negative draft resuluts (under 100% Expected Value).

So we are left with the results! Here are the teams that have gotten the best value for their picks from 2002-2011. Of course, these rankings could all change a lot since the majority of the players are still playing, but this is how it stands today.

Boston Celtics 148.9%
Philadelphia 76ers 147.2%
Sacramento Kings 138.0%
New Orleans Hornets 131.8%
Cleveland Cavaliers 131.5%
Miami Heat 128.1%
Los Angeles Lakers 117.8%
New York Knicks 116.2%
Indiana Pacers 113.6%
Utah Jazz 112.8%

The Top 10 Drafting Tenures as GM (2002-2011)
 The formula I came up to rank the top GM tenures with is overly complicated, but basically it values drafting well over a large sample size. To qualify, you must have at least 5 draft picks. This is a ranking I plan on taking another look at in the future with a wider historical window, since ten years doesn't really do this justice, especially if you consider how many players can still change their evaluation.




Ranking Thomas among the top GM's kind of stuck in my throat, but this analysis is about the DRAFT, not cap room or trades or free agency pickups.

IMO Danny is a high risk high reward GM
He'll draft gems late such as Rondo, Bradley, or even Sullinger, but he'll also draft the fabs and the JJJ's
I think he does a good job

TP for passing along the analysis.  It's interesting to see that several GMs known as being awful at trades and signings rate out very well as drafters.  It's a good thing Brooklyn hung onto all those picks for Billy King to use... :D

thanks ev. good work as ever.

i will now finish plowing through the articles/reading you suggested. i suspect that the analyses will reappear in future threads when, or if, posters lament ainge's draft skills with well researched threads titled "ainge sucks at drafting."   ;D

but now back to the readings....

p.s. i love the otto slam dunk video. really quite cute.

Look at the bright side. We no longer have to read "Doc hates playing rookies" threads.

It is all related though. Doc doesn't play the rookies becasue Danny drafts such bad talent and then it is Doc's fault that they don't become stars because he doesn't play them enough, except the ones he does play and the ones that do become stars.

Melo is going to bring Danny's score down though.  It was a bad pick.  He can't play at the NBA level.  I am not sure how they missed that.

If my team was contending annually, and we had no pick higher than 20, I would certainly want the GM to be a gambler.

I cant really find fault in the Melo draft, most of the players I wanted were drafted prior, so I was ok with the risky pick given that I find no interesting prospect after Sully was drafted

live and lean with Fab.    I was for him being taken ..... I was also so choosing Royce White , and that was a even bigger screwup......on the positive side I was a Sully fan ;D

so lessons learned ...Fab has tools that's all you can evaluate ,  can't  foresee what's in their brain or if they have the mental tuff ness  till they play in the NBA with elites.


win some ...lose some

After reading the articles, remember what the author said from the very beginning of the article about his player ranking system:

Quote
This is a very unfair ranking system, its just for fun. No one is suggesting that these are the best picks of the last decade - they are just the highest value picks at their spots. And since we are ranking players who have yet to finish more than a year or two, a lot of the results will be quite a bit ridiculous.

In other words if you create a system and manipulate numbers that are turn out to be ridiculous, then crap into the system will net you crap out of the system.

Ainge's numbers are skewed by having gotten lucky on some 2nd round picks like Glen Davis, Ryan Gomes and Leon Powe, players chosen late that got playing time and PERs that when multiplied gave extremely large value for the position they were chosen in. That's great but the draft is meant to build and rebuild franchises and you aren't winning many games if you best value picks are Davis, Powe and Gomes.

I love the fact that Ainge can seeming grab a productive role player in the second round every couple of years and that he has hit on some late picks in the first round, but what I want to know is that when given high(lottery) first round picks, which he should be getting over the next couple of years at least, will he not screw them up?

Sometimes, its more important in the top of the draft to just get even value than it is to reach for excessive value. You don't want to be the guy drafting Michael Olowakandi, Greg Oden, Jan Veseley, Joe Alexander, Wesley Johnson, or Johnny Flynn when superstars are being drafted right behind then but "hitting" on guys like Marcus Thornton, Lance Stephenson, Chandler Parsons. Don't get me wrong. Thornton, Parsons and Stephenson are great value picks in the second round that would jump Ainge's score in this very high, but the Celtics need to hit at the top. Ainge has never had to do that. I think his highest draft pick was that he used for the team was Kelly Olynyk at 13.

Any of the GM's numbers could have been skewed by this system if they had made the same "lucky" choices Ainge had made on later picks. Of course, this analysis wasn't made about Ainge, it was made about ALL Gm's.

but what I want to know is that when given high(lottery) first round picks, which he should be getting over the next couple of years at least, will he not screw them up?

I don't know that there's any predictor, accurate or not, that can grade a GM for how they'll do making a pick in a a position of the draft they've never been in. Do we assume he'll screw them up? Based on what information? Will he hit a Home Run? Got me.

All I can tell from the analysis provided, given its perceived shortcomings by some or its accuracy by others, is how Ainge and the other GM's have done with the hand they've been dealt.

Ainge has never had to do that. I think his highest draft pick was that he used for the team was Kelly Olynyk at 13.

I dunno - the problem with putting so much emphasis on the 'skill' at selecting the top lottery picks is that often your choices are far fewer and constrained by context.

Presti didn't exhibit any brilliant skill choosing Durant.   He was the only choice once Oden was taken.

And the choice of Oden - is that an example of a 'poor' draft choice?   Or simply the inability to see the future?  Pre-draft medical due diligence can only go so far.

Basically, in the top 10 or so picks of every draft, the order is usually fairly predictable.  Sure, you have an occasional surprise -- like Bennet going #1 this year -- but even when that happens most of the other top picks still slide into predictable slots based on the teams making the picks.

As much as it is a crap shoot, extracting value out of the later part of the draft is, indeed, over time, the real difference maker.   No - guys like Powe, Davis, Gomes aren't going to be your superstars that carry you to a title.  But they represent 'found money'.  Value that can be used to leverage up through trades.

You say Danny was 'lucky' to find gems late in the draft - and certainly he has.  But when a GM is able to pull an above-average number of contributing players like Rondo, Bradley, Sullinger, Gomes, etc.,  out of post-15 picks, at some point you have to acknowledge that maybe, skill might be a contributing factor.   The fact is, the odds on any pick after #15 being even a solid contributor off the bench are less than 50%.   And after pick #20, they are much worse.    Yet Ainge has managed to get tremendous value of out a lot of post-15 picks.   He's had a handful turn out to be scrap.  But he's gotten above the board value out of the vast majority of those picks.

Since Al Jefferson was taken at #15, Danny has had only two picks in the top 15.  The first one was the 2007 #5 (Jeff Green) who he traded for Ray Allen and the 2nd round selection of Davis.   The other was this last year's #13 (Olynyk), which he got by trading our #16 and change to get.

So far, that looks like pretty good usage of his early round picks.

You are, imho, overly dismissive of the author's methodology:

Quote
In other words if you create a system and manipulate numbers that are turn out to be ridiculous, then crap into the system will net you crap out of the system.

The assessments that the author comes up with are not inconsistent with other analysis that have been made of the NBA draft.   Ultimately, the author's own caveats are meant to point out that there is room for error bars in the final rankings.  The exact rank order should be taken with a huge grain of salt.   But that doesn't mean that the essential conclusions are 'ridiculous'.   It is perfectly reasonable to use it to say, "these GMs over here have been more successful at drafting then those GMs over there".

Here's another analysis that attempts to rate _teams_ (not GMs) for their draft performance from 1989-2008.   

http://www.82games.com/bestdraftingteams.htm

In that study, the Celtics came out #7.    Ainge's tenure only covered a small, 6 year portion of that 20 year span.  The earlier part of that span also includes the weight of such wonderful hits as Michael Smith, Acie Earl, Kedrick Brown & Jerome Moiso -- all of which occured prior to Ainge's tenure.   Smith, Brown and Moiso in particular were all top 15 picks - who ended up providing almost no value.   

NBA Officiating - Corrupt?  Incompetent?  Which is worse?  Does it matter?  It sucks.

Is there a reason that you count the trade of Jeff Green at #5, but don't count the trade of Randy Foye for Raef + Telfair at #6?  Or why you begin your analysis after the Big Al pick, and disregard Marcus Banks at #13?

I don't know why MMMMM skips Banks but from the original study, the author attributes the Foye pick to Portland (under the assumption, the TB's directed Ainge who to pick there?) much as he doesn't credit (or discredit) ainge for picking Troy Bell and Dante Jones in the 2003 draft and then swapping them to Memphis for  Banks & Perkins.

I know the original authors reason for this is on one of the 4 links, but I can't put my finger on it.
