For the first six weeks of the NBA season, every basketball discussion comes with mandatory disclaimers. Don't get too excited, they say. This is a small sample size. Be responsible. Be smart. So one of the best points in an NBA season comes right around now. As of last week, teams all over the league crossed the 20-game threshold. A quarter of the season is already behind us, and among other things, that means we can finally stop qualifying every opinion with a bunch of conditional language about sample sizes. This is a time for takes.
