Joe Mazzulla knew he had to mix things up. With the Celtics down 2-0 after disastrous collapses in the first two games of the Eastern Conference Semifinals in

Is Joe Mazzulla hurting the Boston Celtics? FOX Sports' national radio personality Colin Cowherd didn’t hold back in his critique of the Celtics' head coach following the team’s Game 4 loss to the New York Knicks.

"We had good intentions, we just didn’t execute," says Celtics coach after falling behind in the series against Knicks.

With Mitchell Robinson shooting an abysmal 30% (7-of-23) from the free throw line during the Eastern Conference semifinals, Celtics head coach Mazzulla sees no reason to adjust his Hack-A-Mitch strategy that’s been going for the first three games of the series.

For a change, Sixth Man of the Year Payton Pritchard led all scorers with 23 off the bench while making 5-10 3-point baskets. Jayson Tatum also had a big game with 22 points on 5-9 three-point shooting. The Celtics finished the game hitting 20 out of their 40 3-point attempts, or a 50 percent accuracy.

The Boston Celtics went into Game 3 of their playoff series against the New York Knicks down 2-0. Joe Mazzulla and co. knew that it was a must-win, and luckily for Boston, they pulled it off, getting the blowout victory in New York.

The Celtics insist they know what's wrong with Kristaps Porzingis, but they won't give away any details. Boston Celtics center Kristaps Porzingis has been dealing with an illness that knocked him out of the lineup in March and has forced him to miss time here and there ever since.

The Boston Celtics haven't played up to their potential during the playoffs, but one incredible idea could change that.
