CHICAGO -- Derrick Rose's brother and manager, Reggie Rose, said Thursday that the franchise hasn't put enough quality players around the Chicago Bulls star to win a championship and that could be a "big factor" in whether he returns this season from a knee injury.

Reggie Rose said he was speaking for himself and not his brother.

"What have you pieced together? Have you made any moves? Have you made any trades to get better? You know all roads to the championship lead through Miami," Reggie Rose told ESPNChicago.com. "What pieces have you put together for the physical playoffs?

"Joakim Noah is a great player. Luol Deng is a great player. But you need more than that. You have to put together pieces to your main piece. The players can only do so much. It's up to the organization to make them better."

The Bulls, who stood pat at Thursday's trade deadline, issued a statement from Derrick Rose on Thursday evening.

"I have always felt that the Bulls organization's goals have been the same as mine and that is to bring another championship to this city," Derrick Rose said in the statement.

Reggie Rose, meanwhile, expressed his frustration with the team's lack of movement.

"It's frustrating to see my brother play his heart and soul out for the team and them not put anything around him," Reggie Rose said.

Bulls coach Tom Thibodeau was asked if Reggie Rose's comments could be disruptive to the team.

"Nah, not really," Thibodeau said before the Bulls hosted the Miami Heat. "Obviously, Reggie and Derrick are very close. We share the same concerns about Derrick's health, so that's not anything new. So it's not a big deal. And Reggie's entitled to his own opinion."

Thibodeau said Reggie's comments did not put Derrick in an uncomfortable position.

"To me it's not a big deal," Thibodeau said. "We all want the same things. We want Derrick's health ... and obviously, we're trying to pursue winning a championship. We share that in common. That's his opinion. He speaks for himself, not a big deal."

Pulling off a trade would have been complicated for the Bulls, who are hard-capped at $74 million in payroll this season.
