According to ESPN.com's Dave McMenamin, Lue said, "I need to see more out of a lot of guys."
LeBron finished with 46 points, 12 rebounds and five assists as the Cavs evened the series at 1-1 following a disappointing Game 1 performance.
Aside from James, only two Cavs players scored in double figures, with Kevin Love finishing with 15 points and Kyle Korver netting 12.
Cleveland also got only 16 points out of its entire bench in the game.
Lue tinkered with the starting lineup by inserting Korver and JR Smith over Rodney Hood and Jeff Green. LeBron felt the move paid dividends:
"I think it's just familiarity with that lineup to start tonight. I mean, you got four guys that's played in postseason games [together] before, and you add [George Hill], who's got his own experience as well, so that definitely helps from that standpoint. It allowed [Green] and Rodney to kind of get in and get settled into the game before their number was called, so I think it worked well for us tonight."
The Cavaliers shook up their roster significantly prior to the trade deadline, and James acknowledged Wednesday that it impacted the team's playoff preparation, per McMenamin.
Cleveland is in search of its fourth consecutive trip to the NBA Finals, but this version of the team is far different without Kyrie Irving to lend support to James.
