It's a bad plan because the lottery is such a crap shoot. And, even if you luck out and get one of the greatest players of his generation, he can still leave as a free agent when he gets tired of losing. Again, sucking only guarantees one thing - that you SUCK. I'm tired of losing and want to see some forward progress.
How many of those teams that were built through multiple consecutive trips to the lottery actually won championships? For every team you can name that has made it to the finals by years of sucking, I can name multiple teams that have won championships that haven't.
What you and other call getting lucky, I call being smart. Look at the Spurs. They have won 4 championships and are on their way to the finals and a possible 5th title. They've had exactly one lottery pick in the last 23 years. Since drafting Tim Duncan 16 years ago, they have won those 4 titles without drafting anyone higher than 20. Look at their current roster. Tony Parker was a 28th pick. Manu Ginobili was a 57th pick. Tiago Splitter was a 28th pick. Kawhi Leonard was picked 15th by the Pacers and acquired by trade for George Hill was was picked 26th by the Spurs. Outside of Duncan, their entire starting line -up was acquired via very late 1st round and second round picks. And then they fill out their bench with guys like Gary Neal was wasn't even drafted. You can call that luck, but when it's part of a pattern, I call it smart.
The Cavs sucked for years and won the LeBron sweepstakes and have exactly one finals appearance and zero titles to show for it. OKC had top 4 picks 3 years in a row, have made it to the finals once and are already regressing due to stupid management decisions). And these are the successful teams that were built through the lottery. Minnesota had 7 picks in the top half of the lottery over a 6 year period, is still one of the worst teams in the league and has ZERO playoff appearances to show for it.
Pardon me if I don't like that "plan". We have two solid players to build around in Aldridge and Lillard - one a veteran and one just coming off his rookie year. So, let the building (NOT rebuilding!) begin. Get them a bench and use the 10th pick plus all that cap room to get a solid starting center and a good wing player. From the list above, some of the best centers in the league were taken at 10 or below, and there are always plenty of very solid 2/3s available at 10 and below in every draft. Every year, 1/3 - 1/2 the players in the all star game were drafted at 10 or below. The 10th pick plus a ton of cap space should be enough to get this team up to a 6 - 8 seed next season and then they can fine tune the roster from there.
