Signing Russell Westbrook was an odd move for the Sacramento Kings. To be fair to Brodie, he has actually found a groove and has been playing quite well. But bringing him on board didn't give the Kings the one thing they absolutely needed, and that is direction.
If you get right down to it, every team in the NBA is working towards the exact same goal: winning the NBA Championship. It's more important than personal accolades or glory. And if you're not chasing that specific dragon, you simply should not be in the league.
Westbrook is currently in his 18th NBA season and has yet to win an NBA Championship.
