I'll answer that by asking another question in return: one team in the last thirty years has won a championship without a bonafide Great player. One. And we don't have one... how we gonna get one?
I'll bite.
The last 10 years only 2 top 3 picks have a championship. Duncan and Billups got a ring, but was Billups the "leader"?
The last 20 years you can add Shaq, David Robinson (does he count as a lead or was it duncan?), Zo and Laettner (see D wade and shaq, funny #1-3 in the 1992 draft on the same team), Sean Elliot and Gary Payton won championships, but neither lead their teams.
And now go 30 years you can add MJ, Hakeem, Isiah Thomas and Magic as leading their teams. James Worthy , Kevin McHale, , Bill Cartwright , Mychal Thompson got rings too.
So of the past 90 top 3 picks only 16 have rings I'd say only 6-7 of them were the "superstar" that lead their teams to it.
You realize that the Lakers traded Gail Goodrich to the New Orleans Jazz for the #1 pick, they drafted Magic. They didn't "tank" to get that pick.
So No, a top 3 pick has more to do with luck with who's in the draft then anything. The superstars come along about once every 6-7 years and few of them get rings.
So lets look at the other "Superstars" of the past 30 years with rings and where they were drafted that lead their teams.
Larry Bird #6
Kobe #13 (Was he a superstar then?)
D Wade #5
Anyone have any other "superstars" drafted the past 30 years that have rings?
Oh and look at the list of players, how many were on the team that drafted them?
