The situation he'll find himself in on Sunday won't be all that different - aside from the game being played in Boston, where the Cavs have yet to win this postseason.
And so now we return to Boston on Sunday for a best-of-one series.
James will have another opportunity to showcase his dominance as the Celtics and Cavs take the TD Garden court Sunday night for Game 7 of the Eastern Conference finals.
When the game victor at the buzzer in Game 5 against the Indiana Pacers fell through the net in the first round - a step-back 3-pointer that probably ended up tipping the series in the Cavs' favor - James jumped on the scorer's table to lead the celebration.
He's had a fairly steady 2018 post-season, averaging 14.8 points and 10.4 rebounds but his critics have often insisted he should be doing more.
"We've still got to come out aggressive and play Celtics basketball", he said.
"It's over with now", Brown said.
"To have him on our side, it kind of lets me take a deep breath of fresh air". If the Cavaliers come out on top, they will head to their fourth consecutive NBA Finals. That pre-season script has gone through several edits over the last seven months, with Kyrie Irving and Gordon Hayward both sidelined for Boston and Isaiah Thomas long gone from Cleveland, but here they are.
With Kevin Love out for precautionary reasons for the final 43 minutes due to a head injury - he was being evaluated for a concussion - James also got a lot of help from his teammates. "That's the only thing that matters". "It's not going to be pretty", said Marcus Smart.
James had one basket on four shots in the fourth quarter, and afterward conceded that he was worn down.
Following Game 6, Love told a reporter it was "a toss-up" whether he would be able to face the Celtics. "Now, obviously [if] I get a minute, couple minutes here, per quarter, would be great, but it's not what our team is built on right now". Tatum finished with 15 but was largely a non-entity during the first half.
"The second quarter definitely killed us", Rozier said of Cleveland's 34-18 advantage.
That's when the Cavaliers fought back. Nance to jump up and body checked him; Morris responded with a one-handed shove to the face. "Had a chance there to cut it to 4 on a shot".
The Celtics open as favorites of 2 to 2.5 points depending on the sportsbook. For the first time in this series, the Celtics offense really showed up on the road. People can say what they want.
