CHICAGO -- For the first time since having a meniscectomy on his right knee on Feb. 27, Derrick Rose participated in a full contact five-on-five scrimmage during Tuesday's practice. "He's just got to string some practices together," Bulls head coach Tom Thibodeau said. "Yesterday we established a baseline, and keep building from there. It's just steady progress. He's got to continue to build. He's got a long way to go, and we have to focus in on what our team needs to do so that's first and foremost right now."
