I go Rondo / Hondo back court, Bird and McHale at forwards, and Bill holds down the pivot. I'm going off over all value to franchise plus peak performance.
Ray Allen and KG for their careers might have an argument, just not their Celtic years. Similarly I couldn't put Kareem or Wilt Chambrlain in as starters for LAL, since they spent many years away. 3 of Kareem's four best years were in MIL 71, 72, and 73, in addition to his resurgent 78 season. Of course he was at a high level for a ridiculously long period in LAL, I just can't start a guy whose best years were on another team AND he won a title there. Wilt spent only a few years there. I went with Mikan - he won titles, but he was pre-LA. So maybe Shaq who is similar to wilt, except he played his peak in LA, instead of his sunset.
