The Warriors made the best first impression and take the top spot in the NBA Power Rankings.
Drawing conclusions after just one week of play is like evaluating candy based on smell.
That said, we can nail down a few certainties already. For one, the Los Angeles Lakers are terrible at basketball. Second, the Thunder's playoff hopes are in serious jeopardy as long as Kevin Durant and Russell Westbrook remain in street clothes. And the Warriors -- SI.com's No. 1 team -- haven't missed a beat under new coach Steve Kerr.
Others teams are harder to judge. What do we make of the Knicks after floundering at home their first night but spoiling LeBron James' homecoming in Cleveland the next? Are the 3-0 Heat still an elite team? Have the Suns taken the next step?
Rather than guess, let's just go over what we know. Here are my first impressions in this week's NBA Power Rankings. (All stats and records are through Sunday, Nov. 2. "Last Week" refers to preseason rankings.)
