Well let's look at the championship teams from the last 15 years
Here's where "Let's define tanking" becomes part of the discussion. If you want to say that getting a top 10 pick, or picking in the lottery, isn't "tanking," then that's going to support your argument pretty well.
Warriors - Curry 7th, Klay 11th, Barnes 7th
Spurs - Duncan 1st
Heat - Wade 4th
Mavs - Dirk 9th
Celts - Pierce 10th, traded 5th for Allen
The Lakers and Pistons are your outliers. The Lakers are the Lakers, which helped them get Shaq AND Kobe. In their second Kobe run, they also had Bynum who was 10th.
The Pistons, the true outliers who always get talked about, are the exception that proves the rule. You want to set out to build another Pistons team and win a championship that way, at least acknowledge it's got even fewer examples of success than the other ones.
I've said in the past, it's not all about getting the #1 pick, or a top 5 pick. History tells us picks taken in the top 10 or so are the lifeblood of really good teams.
Anyway, this is small sample size theatre. A more convincing take would be to do an exhaustive inventory of every team that's ever won close to 60 games or more and see how they were all built. I don't have time for that, but my guess is they relied heavily on top 10 picks.
At some point outliers have to considered part of the equation. 2 in 15 makes it more common than a outlier.
I'm not necessarily disagreeing about the top 10 picks thing, but the question is whether or not the Sixers' route is proven and effective. I argue that it isn't.
And by the way, we do have one top ten pick on our roster, and next we might have more.
Limiting it to championship teams and top 3 picks only seems silly to me. Expanding it to finals teams is really where you see the benefit and top 5 picks where historically the talent really drops off makes more sense from a sample size.
Kevin Durant, LeBron James, Kyrie Irving, Russell Westbrook, James Harden, Tim Duncan, Dwayne Wade, etc.
Plus Rose got hurt, which could have been another.
Plus the Cs run began with tanking and trading the high pick.
The Warriors blatantly lost games and got Harrison Barnes.
The Nets made it with KMart.
It has worked. It has failed. Just like every other rebuilding method. For some teams it makes sense, and for other teams it doesn't. To narrow the sample size so much that uit's restricted to Finals winners in a league with like 9 Champions in 35 years seems a bit ridiculous.
