Joakim Noah posted 15 points, 14 rebounds, six assists and six blocks in the Chicago Bulls' win over the Boston Celtics on Friday.

Noah is still regaining 100 percent form physically and is confident he will reach that point this season.

"There is no question in my mind — 100 percent — that I can get to where I want to be physically this season," Noah said. "I have to be positive. I know how far I've come just in the last month."

Noah acknowledged the seriousness of the May 2014 knee surgery, which the Bulls originally termed minor and needing an eight- to 12-week rehabilitation period. Both Noah and the Bulls acknowledged on the eve of training camp that a longer recovery period prohibited Noah from playing full court all offseason.

And Noah has remained on minutes restrictions all season.

"It was more than a scope," Noah said. "That's what it was supposed to be. So it definitely took longer than we expected. But it's nothing that I can't recover from and be back 100 percent and be right."
