collegehoopsnet also has a story about lottery picks and where they came from.
Over the past 10 years there have been 133 lottery picks.
102 of them were college players, 31 have been high schoolers, international players, etc.
Of the 102 college players 83 were from the BCS conferences and 19 were from mid-majors.
(One was from Bradley)
Here are some interesting facts....
Of the 13 lottery picks that came from the Big XII over the past decade, only one has become and All Star (Paul Pierce).
Same for the Pac 10, only one out of 12.
And the SEC, only one All Star out of 11 lottery picks.
Of the 19 mid-major lottery picks, 2 have been All Stars (Shawn Marion, Wally Szczerbiak).
The big producers of lottery picks (and All Stars, too) have been the ACC, Big East, and Big Ten.
They have produced 22, 16, and 9 lottery picks respectively
BUT
none of the Big Ten players has been an All Star!
