Any team that goes 10 years with the same 3 players and goes to the NBA Finals in both 2002-03 and 2012-13 (in addition to others) is surely a great team
These Spurs should be in the same thought as Michael's Bulls, 80's C's/Lakers, Russell's Celts, etc
TP will probably never get the recognition he deserves. If you value team success you could make a case for Parker being a top 10 PG of all time. Although he obviously owes a lot to Duncan.
