I found this paragraph interesting.
Indeed, of the 76 players who have made an All-Star team between 2005 and 2014, only eight were second-round picks (Ginobili, Millsap, Gasol, Carlos Boozer, Mo Williams, Rashard Lewis, Gilbert Arenas and Mehmet Okur). One other All-Star (Ben Wallace) went undrafted. Who made up the rest of the All-Stars? A jaw-dropping 53 lottery picks and 14 non-lottery first-round selections. To underline this point, Lakers guard Kobe Bryant has more All-Star Game selections over the last decade (10) than all currently-active second-round picks combined (Ginobili, Millsap, Gasol, Boozer, Williams and Lewis combine for 9).
So when I read about questions of the worth of high draft picks, I'll keep this in mind....though not all High draft picks pan out, the odds are, a player who makes a difference was one.
