Jaylen Brown made a promise to the Boston Celtics ahead of Game 4 of the Eastern Conference Finals against the Miami Heat.

Brown knows what he and his teammates have to do to even the series.

“Being aggressive defensively is going to be the key to the series for us. Defense is what we hang our hat on. It’s something I hang my hat on. I think I can take it to another level and I will,” the star of the Celtics said, per Chris Grenham of Forbes.

Miami leads the series 2-0. Game 4 is on Wednesday.
