That is my guess too of the Rangers ideas, but we'll see what happens with Boston. If it turns out they end up facing a team more advanced in their rebuild who also drafted earlier than they did, and those top pick are big contributors towards them beating Boston, wouldn't that be some evidence that even if a teams rebuilds like Boston did, and things went well (they received a Pasternak, etc) and still are being eliminated from the playoffs, that it would have been more advantageous for them to rebuild like the team who eliminated them did?
If Boston ends up winning the cup that would be some evidence it's possible to build in such a way to do so, yet if they end up eliminated prior it kind of shows that while that building method can get a team into and even advance in the playoffs, it ultimately comes up short.
Which has basically been my argument throughout the last Rangers build too. Boston won a cup using such methods once, (even if they did have Seguin) the other teams who went more towards the full scorched earth rebuild have won more often. LA did so using a little of both as they picked pretty early for a span of years leading up to their runs, I'm not sure I see that trend changing.
