I don't know, I still think the Warriors are very flawed. They're dangerous if they're hitting a ridiculous % from 3 (i.e. games 1 & 2 last year), but that's not sustainable over a 7 game series. I dare say that Thompson will play his entire career and never hit 90% from in a game again (regular or postseason). The guys they did get will help them match up with the Spurs, but also might take them out of the some of things that that gave the Spurs trouble (extended periods of small ball). They're also completely dependent on one of the most fragile players in the NBA.
That doesn't mean that they can't beat the Spurs. But I think if the Spurs hit next postseason a) relatively healthy and b) don't experience significant drop-off out Duncan/Parker, they'll handle GSW again. Now, if either of those exceptions occur - all bets are off for a le anyways so there is no point in worrying about it.
