Jermaine O'Neal followed up an 0-for-6 performance in Indianapolis on Saturday night with a more representative 12-point, 11-rebound double-double last night. But the Celtics center said he's tired of talking about offense. Contrary to public perception, O'Neal said, scoring isn't why he's here. "There's a lot of misconception, a lot of debate from people who supposedly analyze the game," he said after the Celtics' 97-88 loss to the Thunder. "You have to know what position the team has players in. The fact of the matter is that (coach) Doc (Rivers) has given each of us a role, so all of this debate about what I score — I probably won't even answer that after this time. For all of you wondering about production with me scoring, that's not my role.
