Celtics at Nets

By Bobb Burgess for Boston.com

Details: Boston Celtics at Brooklyn Nets, 12 p.m. (ESPN)

Overview: Earlier in the season these teams engaged in a brawl that spilled into the stands and resulted in Celtics guard Rajon Rondo being suspended for two games. Let’s hope that on Christmas Day they stay focused on playing and not squabbling.

If they do, fans might see a point guard duel worthy of the spotlight: Rondo vs. Deron Williams.

Both teams are chasing the Knicks in the Atlantic Conference with the 76ers nipping at their heals.
