Celtics head coach Doc Rivers says he is not overly concerned about the lower assist totals of point guard Rajon Rondo in the last three weeks. Entering Monday’s game, Rondo averaged 8.3 assists over his last 12 games. He recorded double-digit assist totals in just four of those games.

“I don’t know. Maybe I’ll call [assistant GM, team counsel and stat guru] Mike Zarren and figure it out,” Rivers laughed. “Honestly, bench is playing really well and his minutes are down over the stretch as well. Ball movement is better and maybe it’s a by-product of that, but we can do that and he can still have high assist games as well. It’s just one of those stretches.”

Rivers also spoke about not taking the 9-27 Bobcats lightly. Charlotte started out the season 7-5 before losing 22 of their last 24 coming into Monday’s game in Boston. Rivers also confirmed that big-man Chris Wilcox (thumb) is getting closer to returning, and would dress but not play in Monday’s game as the Celtics need to dress 12 players for the game.
