Rajon Rondo isn't worried about Sam Cassell coming into Boston and stealing his playing time, according to the Boston Herald.

If Cassell does officially become a Celtic on Monday, Rondo will immediately start playing off the ball on occasion, something he did at times in college.

"It?s interesting," Rondo said. "I did it at Kentucky a couple of times, and I actually had my career-high (26 points) one of the times. I?m always up for whatever?s best for the team, and I?d be able to learn while I?m out there watching him as he?s playing the point position. I?m sure there are things I can pick up on."
