"He has a great support system," Thibodeau said on "The Waddle & Silvy Show" on ESPN 1000. "His family is fantastic. They've been great with him.
"He comes in every day. He's diligent. He's moving along well."
Meanwhile, Thibodeau said he talks to Rose almost every day.
"I think he understands what he has to go through, and he's approaching it like he does everything else," Thibodeau said. "His rehabs are his games and practices right now.
"His concentration in rehab is fantastic. He just has to be patient and keep doing what he's doing."
Rose suffered six different injuries during the season, limiting him to 39 games in the lockout-shortened 66-game season. Thibodeau, who faced constant questions about his playing time for Rose throughout the season, said he has no regrets with how he used him.
"I look at it overall and when you look at the season, Derrick played about 1,300 minutes this year," Thibodeau said. "When you look at where it ranks in the league for a player of his caliber it's really low. I think in overall minutes he was like 154th in the league (165th with 1,375). I think in minutes per game it was 28th or 30th, somewhere in that area (actually he was tied for 23rd at 37.0). I think it was unfortunate. It was one of those years where he had a lot of different injuries.
"I don't look back and regret that. I think it's unfortunate, it happened and you just have to move on."
Rose isn't the only Bulls player dealing with an injury. Forward Luol Deng played most of the season with torn ligaments in his left wrist which might require surgery. If he does have surgery, it likely will come after the Olympics because Deng intends to play for Team Great Britain this summer.
"We certainly care a lot about Luol and how he feels," Thibodeau said. "We just want to make sure from a health standpoint that he's good with everything. I think they had a very good meeting, and I think everything will be fine."
Faced with the prospect of being without Rose for much of the season and Deng at the start of the year if he has surgery, Thibodeau said he will approach the season the way he always does.
"You never know how things play out. I never look at it (like it's a lost season)," Thibodeau said. "I always feel like we have enough. We'll figure out what the strengths of the team are. We'll play to our strengths, we'll cover up our weaknesses, we'll try to get better each and every day and then we'll take our shot at the end."
The Bulls recently picked up the option for the third year on Thibodeau's contract and plan to work out an extension. Thibodeau, who finished second to San Antonio's Gregg Popovich in his bid to win a second straight NBA Coach of the Year award, said he is not concerned that he doesn't have a new deal yet.
"I think anyone wants to be recognized as one of the best in their profession, but there's a lot of different ways you can measure that," Thibodeau said. "They've been fair, and I'm hopeful that it all works out."
