The only Spurs players who really have the "experience" advantage are Parker, Gino, and Duncan.
The only vet on the Spurs (5th year or higher) that the Spurs use on a regular basis is Matt Bonner. Diaw and T-Mac are there, but they're mostly on the bench reserve. Especially T-Mac.
Meanwhile, the Grizz have Allen, Connelly, Gasol, Randolph, Prince, Bayless, Dooling and Arthur. All of whom are either in their 5th year as a pro or higher. 2 of whom have championship experience (Prince & Allen).
