If you were to make a team out of the Spurs best castoffs you would have a terrible NBA team. No big time scorer or a real post presence however the team would have a lot of nice pieces that for one reason or another just couldn't work out here...
my current cast off team would look like this
PG: Udrih, Dragic
SG: Hill, Mason Jr.
SF: Gee, Anderson
PF: Scola, Blair
C: Mahinimi, Mohammed
Did I forget about anyone who deserves to be on the list?
