I think we need to seriously have this conversation now.
I feel like there's an invisible wall between "liquid" assets like top 10 picks, equivalent prospects, or all-star level players, who have solid value in any transaction, and then "marginal" assets like mid-late first rounders and role players. No matter how many marginal assets you have, it's very difficult to secure a liquid assets. In simple parlance, Evem 10 dimes won't get you a dollar.
Out of our entire stash of assets, I feel like Marcus Smart, the two Brooklyn picks (and maybe our own picks depending on the direction we go next season), and maybe Isaiah Thomas are the only assets that even remotely approach liquid status.
I hate tanking as much as any sane fan should, but if it is indeed the case that no amount of #16 picks or Avery Bradleys or Dallas 1sts will get you to any asset that has a chance of converting to a foundational player, maybe the Philly method is the way to go. What's the point of stockpiling a "treasure trove" while staying respectable if it can't even bump you up the 4~5 slots you needed to draft someone like Myles Turner? I hate it and I wish it wasn't so, but maybe that's the direction rebuilding in the NBA is going in.
