he had success in one franchise, and their teams choked when things matter most. he wasn't great in Denver, and he wasn't great in New York.
If you took Steve Nash away from the Suns, and he wouldn't have had success there either.
Losing to the SAS 3/4 years in the playoffs (2 of them being championship years for the Spurs) isn't really choking.
The other year he lost to a damn good Mavericks team that probably should have won the finals.
Last year there he lost in the 1st round, and that was after Kerr traded for O'Neal and totally changed the way the Suns could play offense.
