This is from grantland.com (the sports guys website):

Here's the problem: Golden State has never beaten Duncan in San Antonio. Not for 16 solid years. In games he actually played, he's 28-0 at home against the Warriors and 19-6 in Oakland. You read that correctly: 47-6. I'm a big believer in the whole "Certain Guys Just Own Certain Teams" dynamic, and for whatever reason, Tim Duncan O-W-N-S the Warriors. Throw in Golden State's happy-to-be-there vibe in those postgame locker-room celebrations last night and I'm not feeling too confident about the Dubs in Round 2. Regardless, we'll always have Round 1.
