Not understanding all the talk about Wiggins in this context (trading Rondo for a lottery pick). Wiggins looks awesome. But he isn't what this sort of trade would be about.
The absolute max chance any one team will have at him will be 25%.
Whomever ends up with (or looks destined to end up with) the worst record is not trading their pick to us for Rondo. A team tanking that bad wants Wiggins or bust.
So pre-lottery balls, you aren't looking at any chance greater than 20%, which is the odds of the 2nd worst team. And I doubt even THAT team trades you that pick. I think the best chance you might have pre-lottery would be for the 3rd worst team's pick, but that's only a 15.6% chance at #1.
Once the lottery balls are done, then it's even simpler. You are not getting Wiggins for Rondo. You might get one of the other top 8 picks from some team at that point - a multiple-all star player like Rondo is definitely worth a top tier pick. But you aren't getting the #1 pick from whomever got it in the lottery.
So no matter how much you think it might be a good idea to trade Rondo for a lottery pick, there really is only a tiny chance you are doing it to get Wiggins. If you trade Rondo for a lottery pick, it is most likely for a chance at one of the other top 8 players coming out in 2014.
So if you want to ooh and aaah about the potential of what we'd be getting in this proposed trade, you should ooh and aaah about Parker, Randle, et al.
That might make it a harder sell than posting videos of Wiggins.
the thought is if you trade Rondo for future considerations, then Boston will also be significantly worse, like competing for the worst record bad. So say you trade Rondo to Charlotte for the rights to Detroit and Portland's picks. Boston could end up with 3 lottery picks, Detroit and Portland would be late lottery (due to protections) and Boston's own which is top 5 (or better). If the Detroit or Portland picks roll over to the following year, the protections are less and thus could be even better.
If you are really going to purposely tank, I'd rather have Rondo do a Rose and stay on the sideline rehabbing all season and then have him play in the future WITH Wiggins (assuming we were bad enough and lucky enough to get him). If you played the season out right, despite being terrible, you try to bloat the stats (and trade value) of Green as much as possible. Because if you get Wiggins, you'll probably want to trade Green in a package at that point because you don't need two starting SFs (plus you'll probably still have Wallace for another year before he's tradable).
This way, you retain Rondo as a veteran floor leader. You'll have Wiggins and then whatever big star you might be able to get dealing Green, future 1st round picks and other assets for. Rondo + Wiggins + some_big_stud makes for a more complementary core than going completely young. Yes, we want talented youth. But you need veterans to win in the NBA. Plus, the only successful championship model based on drafting a top 3 pick is to add that pick to a team with an existing star and right now, Rondo's our most accomplished star. Plus, really, he's not all that old and should have quite a few great seasons still ahead of him.
Alternatively, if you go through all that (sitting Rondo and tanking) but still end up unlucky with the lottery balls, the chances are that you end up with a PF/C/SG like Randle, Gordon, Parker, Exum or Embiid. Only two of the top lottery projections are PGs right now (though that could change). Again, you would be able to add them to a team that has Rondo and trade the redundant parts from depth.
Note - I'm not necessarily advocating any of this. I'm not a proponent of tanking as I don't think it's necessary. I just think if you ARE going to tank, that the strategy I described is a model that gets you back to a competitive level quicker. You would be trading from depth (the SF/PF/SG positions - which also are the positions covered by 9 of the top 12 picks projected for 2014 at the moment) instead of creating a hole at the PG.
In the less likely chance that you ended up with one of the two top PGs in the projected top 12 (Smart or Harrison), you would probably want them to develop over a year as Rondo's backup and then you'd be trading Rondo at max-contract time.
Depending on the star you brought in, you'd possibly have to trade one of our correlated young prospects. I.E., if you brought in a stud PF/C, then you'd probably have to include Sully or Olynyk in the package. Obviously that would depend on the value the various pieces would have next summer.
I don't expect any of this OR your proposed idea to happen. Of course, I have no idea what the heck Danny could end up doing. There are just a zillion different paths he could go from this point. Too many unknowns ahead.
I even would not be surprised if Danny ends up trading both our 2014 picks away!
The biggest unknown of course is that the current draft projections are basically just vapor. Some of these kids will elect to stay in college another year. Some other kids will come out of nowhere to climb the rankings.
Can you imagine how a team's fans would feel if they tanked hard, maybe even trading away legit talent for other future prospects, got the # pick in the lottery ... and then Wiggins opted to stay in Kansas for his sophomore year? OUCH!!!
