Boston Celtics head coach Brad Stevens was quick to reflect on what went wrong in their Game 4 loss to the Cleveland Cavaliers.

As reported by Scott Souza of GateHouse Media, Stevens blamed the loss to lack of efficiency and poor transition defense:

There is no doubt that our lack of efficiency on offense, and our lack of transition D, were the two biggest difference makers for us. … We'll need to do better in Game 5.

A glimpse at the stat sheet reveals that both the Cavaliers and the Celtics had 10 fast break points. It seemed that the Cavs won the game by outscoring their foes in the paint, 50-38. They also shot 50 percent from the field as opposed to the Celtics, who merely shot 41 percent.

Entering Game 5, Stevens is thinking of mixing up the line up, hoping to find the perfect set of players that can snag that critical win. As reported by John Schumann of NBA.com, when asked about line up changes, Stevens replied:

“I think you do that every day,” he said.

“It's all about trying to figure out if you can be successful offensively and defensively,” Stevens said of lineup decisions last week. “Sometimes you feel like you can be a little bit more successful on one end than the other, but both ends have to be taken into account.”
