OK, let's come up with the plan, then, seeing as how we are prominent NBA executives.
1. Don't do anything before the trade deadline, unless the deal is offered that either converts disposable assets (not in a long-term plan) into young players/picks or allows us to upgrade the assets that are potentially part of the long-term plan.
2. Lottery. Get as high a pick as we can by sacrificing virgins, dancing and such.
3. On draft day, depending on how high our own pick is, how many extra picks might have been accumulated and who is available, some trades could be made.
4. And only now we come to the "money to be spent" part. With so many unknowns (see above), BC won't even know how much money he will have, who he might want to re-sign or let go or even amnesty, until at least after the draft night. Also, seeing as how we clearly aren't the preferred destination for the top FAs, I'd personally hope that he won't take this cap space and use it to overpay for middling quality players again. But regardless of that - now is clearly too early to think of a plan in terms any more concrete than "improving our team long-term while remaining flexible in terms of cap".
