Got 108 (+3) /150
(The +3 is because I couldn't spell Ilgauskas, Szczerbiak or Maggette)
But I have to be honest: I didn't know all of them. When I typed in Brad Miller (for the Kings), I also got Andre (Cavs & Nuggers), Reggie (Pacers) and Mike (Grizzlies). This happened a few time, so my score is inflated. Missed easy ones like Marion, Okafor, Ben Gordon.
I think if you just type in the names of every player who was a star/superstar/scorer/player who stayed on one team for a long time you'll get the quiz done.
