A lot of subjectivity in how to apply any estimate of probability of success. Including what does "make the grade" mean (my term, in this case I meant be a significant contributor to the team that drafted the player).
So the 20% is what I figured was a reasonable rate of success for the pool of 'D' prospects, regardless of the round they were drafted in. If the pool were all 1st or 2nd rounders, I'd expect something north of 20% maybe.
At any rate, I was thinking that 2 out of the top 8 D prospects become significant contributors (let's say 1 top pair, 1 2nd pair) to the Bruins in the next several years. Of the remaining 6, some may get their cup of coffee but not stick, some may flame out, some may turn out to be Trotman, some may be moved before they get any shot with the B's.
Give me 1 top pair and 1 2nd pair (ok, that's 25%, but I can't have .6 of a guy be a top 4) 1 3rd pair, 1 traded for some other need and 2 flame outs and I'll call it a succcess.
I wrote a thread about this a while back, I will quote it here
....
With an influx of prospects there is a bit of excitement/debate over their projections.I don't want to complain about Sweeney/Neely, or to judge which prospects will 'bust' or not. The point of this thread is to simply remove the human element and to statistically analyse draft picks and decide what is a good/ bad/realistic return on our draft picks/prospects.

So let's start by saying on average 19-20% of drafted players make it to the NHL. With seven rounds in the draft, you should be getting one player a year and every third year two players who become career NHL'ers. Getting three players in one draft can set your team up for a decade. For example, Boston drafted Kessel, Lucic, and Marchand in one draft. Tampa in 2011 drafted Namestnikov, Kucherov and Palat, young producing guys that helped put them up to the top of the league.
We all know that not all draft picks are equal, first round picks are significantly more valuable than other picks.
First round picks have a 63% chance of becoming NHL players and second round picks have a 25% chance of becoming NHL players. More recent studies have first round picks as high as 80%, which I believe was buoyed by the 2003 draft class.
But again, not all first round picks are equal. The Bruins picked five first round picks in two seasons; picks 13-14-15 in 2015, and picks 14, 29 in 2016.
As you can see, the probability of picks 14-16 playing 200 games or more is around 50% and the pick 29 is just below 40%. (ORANGE LINE)
So to the purpose of this thread, what is a realistic return on our five first round picks and four second round picks? What is a good/bad/realistic return?
Between Zboril, DeBrusk, Senyshyn, McAvoy, and Frederic, a realistic expectation is that 2-3 players will become NHL regulars and the others will not. Between Carlo, Forsbacka-Karlsson, Lauzon and Lindgren, a realistic expectation is one player will become an NHL player and the others will not. Out of nine players, four would be the average. Five to six becoming NHL players would be great and two (or less)to three would be bad.
So before we pencil everyone in the line up in the future, (Because I still remember Krejci, Kalus, and Karsums destroying the league and I also remember Spooner, Knight and Khokhlachev killing the league), think about this for just one minute. Four guys from the nine picks is a pretty realistic expectation. More than that is great and less than that is bad.
