I disagree with the bolded. Does BPA really exist at all after the first round if they're lottery tickets?
Why have scouts if there's no discernible difference between players picked between 31st overall and 210th, or 31st through 60th? I can't imagine you're suggesting that there's no differentiation between players in those rounds? Based on your scouting reports, your scouts definitely have a BPA each time the team is on the clock.
I used the words "lottery ticket" based on the percentage of those players having extended NHL careers. I was in no way suggesting that all players drafted outside the 1st round are fungible and their potential NHL careers are based on random luck, like lottery numbers.
I'm sure teams have ordered lists of all the draft eligible players in some order of best to worst, but that list is probably dependent on things like long term organizational needs and overarching draft strategy and taking gambles on low floor high ceiling type players.
Even if the draft is fluid, I imagine the list is strictly best to worst. Murray talks about giving each player a score. I imagine their list is strictly best score to worst. I think ties or marginal differences may be broken by the idea of "need," but I don't think the list undergoes sweeping change based on need.
And I'm guessing that list is probably pretty fluid over the course of a draft depending on how things shake out.
I'm sure they do, and I'm saying I think it's generally a bad idea - as evidenced by how quickly our top-to-bottom defense stable went from "stacked" to "biggest organizational need" in about 30 months. What may be perceived to be our biggest need now, may be our biggest strength in a few years - depending on everything from free agency to trades - when these non-1st round picks are turning pro.
Murray's said it over and over: draft well so that you can trade well. I hate the idea of picking a LHD (need) who you have ranked 42nd overall at #38 over a RW (not necessarily a need in that age bracket in our organization) you have ranked 28th. Picking that RW may allow you to move a guy like Fasching or Bailey - or even the pick himself - in a package for a big-time LHD, thereby filling that "need" within the organization.
Unless you're defining BPA as the teams decision on who the best player to pick is all those things considered? Because I doubt teams are going to just draft say 6 centers from rounds 2-7 because "welp BPA we had to take them".
As for your hypo, I'd say go for it. Centers often can play any forward position. What I am against is strict (or general) need-based drafting.
There's certainly some common sense involved as the differentiation diminishes in the later rounds. If you want to draft a defenseman ranked 168th over a RW you have ranked 167th, I don't think it's that big of a deal as we're talking minute chances of having a NHL career at that stage of the draft.
Generally, that's still a BPA strategy with a tiny bit of flexibility and common sense built in.

The fun part in all of this is that we'll never know whether picking only five defensemen in our 20 picks in the first three rounds since 2011 was because all those non-defensemen were BPA or they were drafting for perceived need. I tend to believe it's the latter, but we'll never know for sure.
