Just found this gem and felt I had to address it. You think Rubio is a borderline flop at 5, but Biuyombo and Kanter are not at 7 and 3, respectively are not, "compared to their draft slots"... SMH.
What is obvious from this list though is that:
(a) there have only been only 12 players picked high in recent years, not a large number by any means (that's also an indication of how efficient the system is in grooming talent), and
(b) most of those players do not perform even close to the expectations they were picked with -- Korolev, Sene, Bargnani, Rubio, Kanter, Vesely, Buyombo, and Jianlian all fit that bill. That's 8 of the 11 players that chose to come to the NBA.
That's my definition of flop. Perhaps it's different from yours, but that's another discussion altogether.
Per my response on Biyombo earlier:
Byombo is definitely not a big success for 7th pick, but it's still too early to call him a flop. He's only had three seasons and big men take longer to 'show' in the NBA. He will only be 22 this coming year. He's also managed to record 4713 minutes in the NBA and has respectable per-36 rates of 10.1 rebounds and 2.6 blocks. And those numbers were up to 12.3 & 9 in his most recent season. His DRB% this last season was an excellent 27.6%. So unlike Rubio, he has shown definite signs of progress each year. He may still flop, but it's still too early to say so.
I looked at the numbers for each of the 'questionable' players and tried to compare their overall production relative to their draft class and to their slot. I looked at minutes played, games, points, rebounds, win shares and the trending of efficiency numbers. Since no single number is ever perfect, there is naturally going to be an element of subjective interpretation and evaluation.
I'm not surprised, really, that you've come back with a far more stringent definition of 'flop' -- though it seems vague as to what the exact criteria are. If you could express it formally, perhaps we could apply the same test against all the domestic players to see how they fair?
The 12 international players picked with lottery picks represents 1 in 10 of all lottery picks during that span. Now, as of last year, 1 in 5 players on opening day rosters were internationals (and the trending for that ratio is going up) This suggests that some international players from lower in the draft (or UDFA) are perhaps out-performing their slot.
