Nah. The Spurs don't need PGs. They need folks who can score one-on-one and initiate the offense. Cory, for the hype he's getting, is more of an energy/caretaker type. Look at his Toronto stats:
http://www.basketball-reference.com/...josepco01.html They are worse than they were his last two years in SA.
Don't get me wrong, I think Cory's a better, more actualized player now than he was with the Spurs. But his 12pp36 on 51.2 TS% isn't exactly the missing link here.
The Spurs would be GS by being bigger than them, not by having a slightly better guard than Parker.
