Trading your next five drafts away for anything less than a piece that guarantees your team will be awesome is the kind of move that gets the entire management of a franchise fired and results in the team being in purgatory for a decade.
Does it?
Lakers did it and won a title. Milwaukee did it and won a title. Brooklyn did it once and became a stacked team in 6 years. They did it again and became favorites to win it all. Presti did it in OKC and still has a job. Same for Langdon in NOP and Stone in Houston.
Where are the examples you site?
It's kind of weird to me that you reference Brooklyn and then ask me for examples of what I'm citing .... the current core of our team is the Brooklyn Nets' "future" circa 2015-2020
Let me reiterate what I said
- it makes sense if it makes your team awesome / sets you up to win a title
- otherwise you're setting your team up for purgatory
Lakers -- won a title, but now appear to be in purgatory
Milwaukee -- already a contender, Holiday solidifies them, they win a title, maybe more to come
Brooklyn -- in purgatory for most of a decade, then they leverage their franchise location and their willingness to sign over the franchise to a couple of weirdos to become a title contender and ... haven't won anything yet. To me this is 100% not a path the Celtics franchise could ever hope to replicate, for many reasons.
OKC -- they traded a bunch of picks for George, it got them nowhere. they still have their own picks, though. I don't recall all the transactions they've made, but I think they've reacquired some of their own selections. at any rate, they had to tear their whole team down and are in an extended rebuild. also they have one of the savviest GMS around ... not sure our guy is on that level.
The Pelicans and Houston are also in extended purgatory so I'm not sure how they are positive examples ....
