Thoughts:
Spurs are no threat to the Dubs at this point. Neither are the Wolves because Thibodeau runs his players into the ground well before the playoffs. Cavs are always going to be a threat simply because LeBron but he won't have the chemistry crystallized enough by that point. And although the Raptors look good, especially defensively, I don't think they have enough 'big game' experience.
The Rockets are a concern and have a legitimate chance but I don't buy them winning out in a 7 game series unless the Dubs get bored or lose focus. The Celtics have a chance because of the one major detail you didn't mention -- Brad Stevens; best coach in the league right now. And finally, as a Dubs fan, I'm most concerned about the Thunder -- when that team is playing hard and fast, they're a tough match up (even despite that last shallacking the Dubs gave 'em.)
All in all, fun post!
We all have our own opinions, so I'm glad when someone writes a comment!
It will be a very interesting season! :)
