Sorry, I can't talk you off the ledge because I've been saying this since they lost to Memphis in the first round a couple of years ago. Unless, KY takes some huge steps forward, they don't have a second go-to guy. Miami really exposed how great pick and roll defense can stop the Spurs from playing their game. It will come down to individual players making great plays in the playoffs. Parker, as great as he is, can only do so much by himself when the entire defensive scheme is to stop him. Duncan still shows greatness from time to time, but you're depending on him to make 15 foot shots, not to dominate the paint, and that can be stopped.
So in a game like today, where every possession is critical in the last few minutes, the opposing team has to stop Tony. The Spurs will have to stop Durant and Westbrook, Lebron and Wade, or Chris Paul and Griffin, etc. We end up giving it to Manu to dump it into Tim at the last second who then shoots up a prayer.
