I think following the Wolves, Spurs, Suns and Hornets loss OKC's struggles are because they severely lack size and true shooters,

Wiggins and Joe are played off the floor for example and they have too many developmental projects, SGA, and the rest of the 3 are making wayyy to much money and the championship isn't an excuse,

Shai is overwhelming, Jdub is streaky, and Dort is also more streaky and is a slower shooter, Dick and Knecht would've helped solve the shooting problem entirely,
