this team is still a few years away from even sniffing the playoffs
Everything else you said was spot on, but this is sadly not true. This current mess could simply string a few wins together and be in the playoffs. This current Eastern Conference landscape is just historically bad.
We certainly WOULD have made the playoffs if we stuck with Rondo and set that as our goal. It's obvious we are tanking now, which only about 7 teams appear to be doing in the NBA right now (4 in the East). Making the playoffs was entirely possible and probable. Miami and Indiana are terrible. We've shown we can compete with the best in the East but now choose not to.
It's depressing, but given where we are, it'll be good to trade off spare parts and get some loose change for them. It's gonna be a long season.
And what does sliding into the 8th playoff spot 10 games under .500 get you? Besides putting you behind 5 or 6 western conference teams that are better than you. It certainly doesn't put us closer to an eventual championship.
If we string some games together and back into the playoffs, fine. However, I wouldn't make that "the goal" and make short-term moves. "The goal" is to contend for championships not contend for playoffs.
