Nick Collison just retired last year only played for the Sonics/Thunder (Manu also did with the Spurs). Haslem is probably done after this year, so he will join Dirk in retiring having only played for 1 team.
In addition to Curry (draymond and klay also have shots at it with the Warriors), I think Lillard has a pretty good shot at it. Wall is basically untradeable for awhile, so he might get there by default. If Kemba Walker re-signs this summer he might very well be in Charlotte his whole career.
