The other thing is that Elrod's article doesn't address how these teams acquired their franchise superstars. I'd guess that the vast majority got them through the draft, and almost all of the remainder acquired them by trading lottery-level talents that they acquired in the draft. Still, the fantasy that the Celtics could sign a free agent or duplicate the Kevin Garnett trade, without a top pick in hand, will persist.
The "fantasy" exists because, by my rough count, close to half of the players in the "top players" lists since 2000 are outside of your "vast majority".
Yet still the vast majority that weren't acquired in the draft were acquired by trading draft assets.
Lakers --> I don't think the Celtics can hope to emulate the Lakers, due to a variety of factors.
Spurs --> Duncan
Pistons --> You have to get very lucky to assemble a collection of talent like that and have the more-talented teams run into bad luck / implode; I also think the new CBA militates against collecting multiple stars like that Pistons team did.
Celtics --> Pierce; Allen was acquired w/ the #5 pick; Garnett never agrees to the trade if not for Pierce + Allen.
Mavs --> Dirk
Heat --> LeBron + Bosh never come to Miami if Dwyane Wade isn't there already.
That's just the championship teams, of course.
Lakers --> Lakers won initial titles with Kobe as a key ingredient, however that's pretty much irrelevant because they never would have won those titles without Shaq, who (IIRC) was signed in free agency. The second run of titles wasn't achived until Gasol, Odom, Artest were added.
Spurs --> Duncan is one valid (and very rare) example of a team that won a title shortly after drafting a top prospect. It is the exception rather than the rule.
Pistons --> Bad luck? The Piston's were one of the elite teams in the league all season long and were one of the best defensive teams in recent history. Today's equivalent of their roster would be something like John Wall, JR Smith, Nicholas Batum, Lemarcus Aldridge, Omar Asik. Not a single superstar, but a couple of fringe All-Stars. They knocked off the Lakers Super-team which was about today's equivalent of the new-look Nets or Heat. Luck had nothing to do with it, that was a great team.
Celtics --> Pierce was drafted by Boston...about 10 years prior! The Celtics went through years of mediocrity with Pierce (their superstar draft pick) on the roster, and it wasn't until Ray and KG came along (via trades) that Boston became a serious contender. Ray's draft status is irrelevant...he had been though 2 or 3 teams before coming to Boston and his value was well known.
Mavs --> Dirk came to Dallas via the draft yes...but (as with Pierce in Boston) he was in Dallas for about a decade before they win that title. Once other guys (like JJ, Chandler, Terry, Kidd) were added it put them over the edge.
Heat --> Wade was drafted in Miami, the heat were garbage unti they managed to get Shaq, who was still in the last year or two of his prime dominance. Wade was the #2 player on that team, and after Shaq left they again fell back to mediocrity until they managed to pull Lebron and Bosh in (both via free agency, not by trading picks).
Truth is, there is really only one single case I can think of in the past decade where a team has drafted an elite player and won a title within a couple of years withing adding any other elite players - that was San Antonio with Duncan.
The Thunder are the next closest as they have made the finals through draft success, but it took them several consecutive successful drafts (and a LOT of luck with health, etc) to achieve that, and they still have no title.
Take a look at the teams who drafted in the top three for the past 10 years:

Facts:
* Only 1/20 teams has won a championhip (Miami)
* Only 2/20 teams have made the NBA Finals (Miami, OKC)
* Only 4/20 teams made it past the first round of the playoffs last season (Miami, Chicago, Seattle/OKC, Memphis)
* Only 9/20 teams made the playoffs at all last season
This history suggests to me that if this year's Celtics are bad enough to get a top 3 lottery pick, we probably will not have a serious playoff team for at least the next 5 (maybe 10) years.
Our future first round picks from Brooklyn, LAC and ourselves already have value. Worst-case scenario (from a draft perspective) we end up a fringe playoff team and choosing at around 12-20 n the draft. That gives us the potential to draft players like Kylly Olynyk, Jared Sullinger and Avery Bradley - guys who all have pretty solid trade value right now, epecially as part of a package. If we can draft 3 or 4 guys of that calibre over the next few seasons then that potentially gives us 6-7 young, talented players who we could either:
1. Use to fill holes on our team
2, Package in a sign-and-trade for a star player entering free agency
3. Package in a trade for a high lottery pick
4. Package in return for cap relief that could be used to sign star players
All of those options are IMO better than gambling everything on a lottery pick, and one of them requires having to endure the unplesant nature of being a losing team.
