Westbrick ruining Lakers season

Is Russell Westbrook ruining the Los Angeles Lakers season? He is currently averaging 18 pts, 8.1 rebounds, 7.8 assists and 4.1 turnovers while shooting 43.7% from the field and 29.6% from behind the arc. This by far is one of his worst seasons numbers wise and play wise. He has made Shaqtin’ A Fool many times and has made some of the dumbest decisions in game. Last year without him they were 42-30. This year with him they are 23-24 and under .500.
