Celtics Lead 3-0 in NBA Finals

Compelling Headline: "Celtics on Brink of Banner No. 18, Mavs' Season Hangs in Balance"

The Boston Celtics are on the cusp of their 18th NBA championship, while the Dallas Mavericks are desperately trying to prolong their season.

The Celtics have a 3-0 lead in the best-of-seven series after winning Game 3 in Dallas on Wednesday night. They can clinch the title with a victory in Game 4 on Friday night in Boston.

The Mavericks are facing elimination, but they have shown resilience throughout the playoffs. They have come back from a 3-2 deficit twice already, in the first round against the Utah Jazz and in the second round against the Phoenix Suns.

Thursday night's game is a must-win for the Mavericks. If they lose, their season will be over. But if they win, they will force a Game 5 on Sunday night in Dallas, and keep their championship hopes alive.
