Too early to tell, Spurs' current surge has literally been against a bunch of ty teams, at home, tbh..every opponent has been poor defensively, too, including the Cavs(only the Bulls rank in the top 15 in D, and they were missing 2 of their 3 best defenders)..
The West is pretty overrated, as it is every year, though..there's really no way teams like Portland, Houston and Dallas have any chance at making the NBA Finals

..still, though, Spurs need to show more against better compe ion, we need to see what they look like on the road, especially, since the playoffs is going to be a road gauntlet..
