the main problem i have with sabotaging the team so we can lose more, and thus, gain a greater chance at a high, oh lets say... a top 5 lottery pick, is this:
in the ENTIRE HISTORY of the lottery (22 years) only 4 teams have won a championship WITH a player THEY PICKED in the top 5 on the roster the year(s) they won the nba title. the spurs lead the way with having drafted david robinson first overall in '87, sean elliott 3rd in '89, and tim duncan 1st in '97 (sean elliott actually left for one season, '93-94, then was picked up again as a free agent in '95). all 3 guys where apart of that first championship in '99. the bulls, through trades, ended up with the 5th pick in '87, scottie pippen. the pistons had the grizzlies' pick in '03 (one of the the grizzlies' many many top 5 picks) darko milicic as the 2nd overall pick. they of course won the next year. and most recent, the heat drafted dwyane wade as the 5th pick in the '03 draft and won in '06.
furthermore, only 3 other teams won conference titles with a top 5 lottery pick on the roster: the magic with shaq, the nets with kenyon martin, and the cavs with lebron james, all 1st overall picks. A wopping two 1st overall draft picks, since the lottery, have won chaimponships with the teams that drafted them.... the spurs' david robinson and tim duncan.
my point in all this is simple. losing more games so you can have a higher pick is.... well its just plain stupid. getting a high pick doesn't necessarily mean the future is bright. in most cases it means your franchise SUCKS. sabotaging accomplishes nothing other than turning you into a clippers(historically speaking) type team. losing can become a habit, and its a hard one to kick.
This is one of those cases where its not clear whether you are being intentionally deceptive or just accidentally so. You actually could not have picked a statistic worse suited to your contention -- historically nearly EVERY title winner has had its own Top 5 pick at the helm.
In the 22 years since the lottery was created, you know how many teams have won a title without at least one Top 5 pick that they drafted themselves on their roster? Two. A single team that won a single title (Detroit -- and even they had drafted darko, I just choose not to count him), and then the Lakers who had the singular advantage of being the Lakers and therefore being able to sign away somebody else's superstar #1 pick (Shaq). Nobody else has that chance. 18/22 champions in that era have drafted their own Top 5 superstar.
Your restriction to players drafted in the lottery fails because it does not take into account that for all the early years of the lottery the dominant guys/teams were guys who were drafted before it started. Guys drafted in the lottery itself did not start having real shots at titles until the mid-90s.
