Would OKC been better off trading Westbrook?

[snively]

That's probably true.

I think Westbrook's battling a zero-sum game on the thunder, though, since everyone in the basketball world has been riding Durant's wave since he showed up on our radar screens at the college level.

You can't blame Saint Kevin for anything, so any problems with the Thunder are falling, will continue to fall, and will forever fall square on Westbrook's head.

Westbrook deserves much of the criticism he gets - he was the least efficient of the Thunder hydra last year, clocking in 5+% in TS% behind Durant and Harden, but he still used up more possessions/shots than them.  He regularly called his own number instead of getting a higher % look for a teammate.  He was also a big reason why they were one of the league's worst turnover teams.

That's not to say he isn't awesome in other categories - a fantastic rebounder, a one man fast break, a devastating slasher, an improved mid-range shooter, and a lock-down man defender when he's on his game.

He's a great player but flawed, and his flaws can often be quite detrimental to his team.  That's why he gets more criticism than guys like Durant and Harden, who generally do less that hurts their team.
