CLEVELAND, Ohio -- Nineteen turnovers will get the Cavaliers beat Wednesday in Boston.

They're aware.

"We can correct it," coach Tyronn Lue said.

Cleveland gave the ball away 19 times in its 111-102 win in Game 4 over Boston.

In this Eastern Conference finals, where the home team has won every game, only the Cavs could've coughed it up that much and won on Monday -- because the game was in their building.

When the series moves back to TD Garden for Game 5 Wednesday, the Cavs also can't do there what they did the last two times they were in that building. They can't loaf and fail to communicate on defense.

Fixing those issues was one of the ways they won the next two at home to tie this series at two. Boston was held to 39 and 41 percent shooting, respectively, in Games 3 and 4.

"Obviously we were a lot better defensively, flying around and making them take contested shots and making them make the extra pass," LeBron James said Monday, 44 points and a victory in hand.

"Our communication level has been up obviously in the last two games," James said. "As loud as it is in the Garden, we've got to be able to transfer that energy and that communication in order for us to be better than we were in Game 1 and 2."

If you believe there is no such thing as momentum in the playoffs, that the highs and lows, the surges and streaks and lifts from home fans stop at the final buzzer and don't carry over, then the conference finals are still trending Celtics.

Two of the last three games are in Boston, where the Cs are a perfect 9-0, and these turnovers the Cavs are committing all series are simply not survivable on the road (there were 15 miscues in Game 2, and overall the Cavs have 59 turnovers to Boston's 42).

The Celtics were beaten soundly in both games at The Q, with Game 4 appearing closer than it should've been only because of the turnovers and a little better night shooting 3s (9-of-28 instead of 6-of-22 in Game 3).

But Boston doesn't have to worry about winning a game in Cleveland -- yet.

If there's a team that should be grown up enough to win a tight, tough, loud game on the road, it's the veteran Cavs led by James, who until the 2017 Finals had pushed his teams to at least one road win in 30 consecutive playoff series.

James is flanked by three other champions in Kevin Love, Tristan Thompson, and JR Smith; a fourth player in Kyle Korver who was on the Cavs' Finals team last year; and George Hill, who's played in 95 career playoff games.

Whereas three of the Celtics' top players are rookie Jayson Tatum, second-year man Jaylen Brown, and third-year man Terry Rozier -- the Cavs have maybe the ultimate playoff killer in James and a bunch of adults around him who should be able to handle this.

James scored 44 points in Game 4 (with seven turnovers). It was his second game of 40-plus points in this series and his sixth this postseason. The ball was in his hands for much of the second half as the offense kind of ground to a halt.

Cleveland only had 15 assists on 41 field goals for the game (so, yes, more turnovers than assists) and Kyle Korver scored all 14 of his points in the first half -- but this was one of those rare occasions where this is how the Cavs wanted to play.

In part because of the turnovers and also because the Celtics were moving better on both sides of the ball after a terrible first quarter, coach Tyronn Lue sought to grind out this win with long possessions and lots of drives to the hoop late in the shot clock, often by James.

If the Cavs can cut their mistakes and play defensively in Game 5 the way they handled themselves in the two games in Cleveland, they have James to win it for them late.

"I thought that had to happen," Lue said of the way the Cavs ran their offense late in Game 4. "I thought we got a little stagnant in that fourth quarter, but we wanted to go to LeBron in that fourth quarter. They're switching a lot of stuff, and when they're switching you're going to be stagnant."

James only had three assists in Game 4 for his lowest assist total of the postseason. He shot 28 times and made 17, and only one basket was a 3. So James spent his evening bulldozing toward the hoop, knocking down a few jumpers, and getting to the foul line.

In the Cavs' 107-94 loss in Game 2 (in Boston), he scored 42 with 12 assists and took 29 shots.

"He's doing great things," Boston's Al Horford said. "But for our group, we need to be better trying to contain him. He had a great game (Monday). We have to find a way to be better at home."

Count Lue among those who don't believe in momentum carrying over in the playoffs from game to game. If the Cavs do have any momentum now, it's that they've seen over the past two games how they need to play defense Wednesday in Boston.

Defend, limit the turnovers, get the ball in James' hands in a close fourth quarter, and it's enough to steal Game 5 and maybe this series.

"The real test is how we're going to play out there in Boston," Thompson said.

"We don't know what we're going to see in Game 5 -- only the game gods know that," James said. "We just have to have our same mindset when we came home for these two games. If our minds are there, we put ourselves in a position to be victorious."
