Nope.
I think that would be a serious mistake at this point.
We have young talent already on board and potentially (assuming no Love trade or similar) are about to add more.
If we don't trade that talent now, then if we 'tank' again, you are talking about riding Sully and Olynyk through yet _another_ losing season. That will mean again, purposefuly avoiding fixing obvious holes in the roster and making questionable player utilization choices all in the goal of "development" as opposed to "winning".
The end of that will be that Sully and Olynyk could end up with flatlined or crushed player values and possibly even Rondo walking out the door.
The 2015 draft looks very promising in early projections, especially with some strong, true center candidates. But the latter could be pretty deep throughout that draft. Unless you are dead set on trying to tank for a Jahlil Okafor or Karl Towns (which will require "going all 76ers" for the pick), you can still expect to get one of the serveral other quality bigs (like Turner, Diop or Hammons) later in the 1st and even early in the 2nd.
Next year's draft may not have the hype this one has had, but it looks to be a pretty good draft.
Aside from our own pick, we'll have the Clips' pick and whatever the protected Philly pick vests into. That will either be multiple shots at hitting big on one of the later picks or could potentially be traded up into the low lottery.
I don't see any reason to 'tank' next year, even if we don't "score" with a big superstar acquisition.
Just play to increase the value of the assets we have at this point. If there are solid opportunities to improve the team with mid-level acquisitions (that don't tie Danny's hands long term), then we should do them. Get better. Try to make the playoffs. Build from there.
We have plenty of picks from other teams over the next few years. Someone else is going to stumble and fold for us along the way and the result will be a nice high pick. I'm looking at YOU, Brooklyn 2016. It would be best if we had an already strong roster to add that young player to.
I really don't understand the angst over not getting a chance to draft some hot shot prospect out of school. Even now, the fact is, we can't take everybody in the top 10 - we have one pick- so some fans are going to be disappointed when we don't pick their favorite binky. The rest of those guys are going to our competition. Chances are very high that a large number of those guys will be available via trade or FA in a few years anyway. You just want to be in position with assets and financially to get them when they do.
