There are 7 teams that could make a case for the first seed this year. I’m not sure that the eighth seed goes to OKC. The Spurs still exist, the Mavs are coming up, as are the Kings.
I said 'could', not would; though I wouldn't count them out. They still have a nice roster with a lot of depth:
C: Steven Adams*, Nerlens Noel
PF: Jerami Grant*, Mike Muscala, Patrick Patterson
SF: Danilo Gallinari*, Darius Bazley, Abdel Nader, Deonte Burton
SG: Andre Roberson, Dennis Schroeder, Terrance Ferguson, Hamidou Diallo
PG: Russell Westbrook*, Shai Gilgeous-Alexander
Although we're obviously a better team, like us, OKC can withstand injuries (especially with their backcourt).
