What an unreal team. And they have been almost 100 percent healthy from the beginning of the season. I don't see anyone beating these guys. 
Do you really think they're going to stay healthy for the whole season?
I don't.
Timmy's got to miss some time, and Manu probably will at some point as well. Once they hit 50 wins or so, they'll struggle to maintain intensity. I expect them to finish with 65 wins or so.
I also have a feeling the Spurs have big "Patriots" potential, in the sense that they might own the regular season but then fizzle out sort of quickly in the post-season, either due to age or because they just aren't really built for grind-it-out playoff series.
