I REALLY didn't want to go down a rabbit hole, so naturally I went down head first. I looked back since the 2002 draft to satisfy myself (you know, with an answer...) regarding what percentage of top 11 picks made it into the top 4 within 5 years. I went from 2002 to 2019, as those drafted since have the ability to still get there.
There were 59 (or 62; I may have forgotten to include '07) d-men drafted in the top 11. Of those 37 made it to top 4 status in 5 years or less. There were some (like Nurse) who made it but took a little longer. The d-men in the 02, 03, and 04 draft kinda got screwed by the '05 lockout. There are some you can argue weren't true top 4 dmen. Those I included:
1. Jack Johnson
2. Zach Bogosion
3. Luke Schenn
4. Ryan Ellis (certainly top 4, but whether he really achieved that by his 5th year is debatable)
5. Erik Gudbranson
I think all the aforementioned were in top 4, though there might be an argument to exclude them. There may be a couple I would have excluded that others might not. So approximately 2/3 will be quality in the not to distant future.
Inclusions:
02 - Bouwmeester, Pitkanen, Whitney
03 - Suter, Phaneuf
05 - J. Johnson
06 - E. Johnson
07 - Doughty, Bogosion, Pietranglo, Schenn
09 - Hedman, OE-L, Ellis
10 - Gudbranson
11 - Larsson, Brodin, Hamilton
12 - R. Murray, Rielly, Lindholm, Dumba, Trouba
13 - Jones, Ristolainen
14 - Ekblad
15 - Hanifin, Provorov, Werenski
16 - Sergachev
17 - Heiskanen, Makar
18 - Dahlin, Hughes, Bouchard
19 - Byram, Seider
You want to know who didn't make it, look it up yourself. I wasted WAY too much time on this.
