The Celtics  made a late-minute switch before their game against the Bulls on Friday with Brandon Bass  inserted into the starting lineup ahead of Jermaine O’Neal . Celtics coach Doc Rivers  said he’s been thinking about the switch since training camp and he’ll probably use that starting lineup 70 percent of the time.
“It was a lineup that I wanted to get to because I thought it gave us more versatility and I thought our rotations were easier when you bring in Jermaine in for Kevin [Garnett ], you stay big,” Rivers said. “What I’m trying to do is always have Jermaine or Kevin, just size on the floor.”
It’s not a change in minutes. Bass will still play 25-30 and O’Neal will work about 20-25 minutes. The starting assignment will be based on matchups and against the Bulls who start two big forwards in Carlos Boozer and Joakim Noah  it made sense to counter with the Celtics’ top big forwards. O’Neal may start on Saturday against the Pacers who have a traditional center in Roy Hibbert .
Rivers also said that he was working though his rotations for Garnett. His five minutes on, five minutes off plan sounds good in theory, but Garnett is a rhythm player and the coach admitted it was tough to take him off the floor when he starts to find it.
“I still like it,” Rivers said. “I don’t love it but I think it’s something that we have to do.”
