Add Russell Westbrook to those who speculate Derrick Rose will return on his surgically-repaired left knee sometime this season.

"I see that he's getting better," the Thunder's All-Star point guard said. "He's almost close to coming back."

Then again, Westbrook said he hasn't talked much lately with his summer workout partner. So as with most things regarding Rose, who knows?

This is for sure: The Bulls offense, dead on arrival Sunday night at Chesapeake Energy Arena, could use him badly. Posting season lows for shooting percentage, field goals and assists, the Bulls meekly fell 102-72 to the Thunder.

The Bulls also lost Taj Gibson to a sprained left knee in the fourth quarter. He will undergo further testing on Monday in Chicago.

"The way we competed was embarrassing," Joakim Noah said.

That's three times in the last five games that the Bulls have failed to crack 73 points. The Bulls needed a late rush to avoid the franchise record of 23.4 percent shooting, set during a franchise-low, 49-point debacle against the Heat on April 10, 1999.

As it was, they shot 29.1 percent with 14 assists and 25 field goals. In fact, the Bulls' offensive highlight was Rose working himself into a lather during his pregame workout, including several dunks.

"We have to be mentally tougher," coach Tom Thibodeau said. "When you face a little adversity and you're short-handed, you have to dig down and get the job done. Our level of intensity has to be much higher. And we have to get that right quickly."

Not surprisingly, Thibodeau and players rejected the notion that without Rose and Kirk Hinrich, who sat for the 10th time in 11 games, they are wearing down mentally from the burden of playing short-handed.
