When is the last time a team has done this? But the Celtics have the chance to accomplish just that tonight. They have already beaten the Spurs in San Antonio, and snapped the Houston Rockts' 22 game winning streak. I would think of the 3, the Mavericks don't seem as tough a foe. They don't have the physical presence in the middle to matchup vs Garnett, and Dirk Nowitzki's play has dropped off from his previous mvp levels. Let's sweep the triangle! I'd love to know when the last time this was done by the Celtics or any other team. As it would be an awesome accomplishment if it happes tonight.
