The weekly NBA rankings are determined by opportunity and performance. For this week---ATL/DEN/DET/HOU/MIA/MEM/OKC/POR/TOR/UT all have just 2 games on the slate. The rest of the teams have 3 games for the week and that changes things a lot. Someone as dominant as James Harden is moved down 10 spots because of the lack of third game (and other drama surrounding him being in Houston).
A point system is used that weighs specialties like steals, blocks and three-point shooting a bit heavier. Percentages are not looked at as strongly, but are still taken into consideration. Multi-category producers will always get a bump in rankings as long as they have full slates. Injuries will occur, but knowing what we know at this moment, here are the players that will help you get off to a fast start.
