"It's very important for our guards to be aggressive no matter if they're making shots or not we want them to be aggressive," James said.
George Hill and J.R. Smith had their best game of the series yesterday.
Hill and Smith each scored in double digits against Boston for the first time this series.

No. 23 said when the guards attack the rim it keeps the defense at bay.
"It allows me and Kev to have more open lanes as well. When those guys are aggressive looking for shots," James said.
James mentioned how Hill's play took pressure off him and Kevin Love.
"He had an aggressive mindset that they are going to slide under his pick and rolls he's going to shoot it. He gets a swing, swing, he's going to shoot, he's going to attack," James said.
The Celtics lead the Cavs in the series 2-1. Game 4 of the series will be played at Quicken Loans arena at 8:30 p.m. on Monday.
