Tom Brady Narrates Celtics' 'We Want Boston' Hype Video Ahead of NBA Finals vs. Mavs

The Dallas Mavericks have officially been warned.

The Boston Celtics released a hype video ahead of the NBA Finals on Wednesday that was narrated by the one and only Tom Brady.

After the video opens with frames of opposing fans chanting "we want Boston," Brady says, "Really? You want Boston? Take it from me. That's a bad idea."

It even snuck in a shot at the New York Knicks with video of their fans chanting that they wanted the Celtics even though they lost to the Indiana Pacers ahead of the Eastern Conference Finals.

As Brady explained, every team in the playoffs that has asked for Boston thus far has come to regret it. The top-seeded Celtics steamrolled their way through the Miami Heat, Cleveland Cavaliers and Pacers while losing a combined two games and now have their sights set on the Dallas Mavericks.

Luka Dončić, Kyrie Irving and Co. will be a more daunting challenge than the shorthanded teams the Celtics dispatched in the Eastern Conference playoffs.

But Boston finished with the best record in the NBA for a reason, and it has home-court advantage in the Finals as a result.

The chanting from opposing fans hasn't worked to this point. It will be up to Dončić and Irving to change that.
