I do like that the 1st round is excluded from this. From the 2nd round on every team had a chance to pick every player, so draft position, while not eliminated, is minimized some.
I also think that by keep comparing and throwing out names of guys drafted by teams is doing a disservice to heart of what this data is showing and what (I think) Riptide is trying to show. He's not trying to show that Holland found better players later than Shero. He's trying to show that Shero didn't do a very good job using the draft as the base roster building tool that it is. So he was able to offset some of those mistakes with trades which is awesome, but there's a lot of luck involved in that. You have to have a willing partner, a market for the player, the player has to show some kind of talent, you have to have a team with a need/want for that player. It's not like any bust you're going to find a monster trade to pawn him off in. There needs to be a (somewhat) perfect storm to move those mistakes.
These numbers are showing that even though it's unpredictable, it's not as unpredictable as a lot of you are making it out to be. It may be a small sample size, but there's enough teams getting/finding a ton of NHL value to at least lead me to believe it's not the crap shoot it's being portrayed as by some people.
If it was just 1 or 2 teams getting a lot of games out of the draft, sure, then you can say it's really a shot in the dark and maybe UDFAs would be a very good way to go... BUT San Jose, LA, Columbus, the Rangers, Minnesota, Nashville, Toronto, and the Islanders have all be able to amass over 1000 games played by players drafted by them in rounds 2-7. While all those games haven't been accrued on the team that drafted them, the player picked was good enough to get those games in the NHL with some team.
Now imagine if Shero was able to bump up his "Riptide Draft Numbers" with the base he had on the Pens. There wouldn't have been a need for $1.2mil on Payett, $1.1mil on Tanner Glass, $1.05mil on Cal O'Reily, $2mil on Tyler Kennedy, or anything on Craig Adams. Maybe there wouldn't have been a harsh a cap crunch last year and wouldn't have had to maneuver salary just to add a league minimum Kobasew. There's some savings to be had had Shero been able to pluck some usefulness out of the drafts being looked at. **Of course this isn't taking into account how "The Coach Who Shall Not Be Named" would have used those players**
