MIAMI — As the final horn in a Game 6 loss to the Indiana Pacers was sounding, LeBron James walked toward several of his Miami Heat teammates to shake some hands and share a couple of quick words.

His message was clear: Get ready for Game 7.

Here comes the ultimate game. To the winner, a trip to the NBA Finals. To the loser, an offseason loaded with regret. It’s that simple now for the champion Heat and the confident Pacers, who meet in Game 7 of the Eastern Conference finals Monday night in Miami.

“Each and every year there are 30 teams that would love to be a part of this, to have one game to advance to the NBA Finals,” James said. “And there’s two teams that’s in this position. And it’s something that you can’t substitute, this feeling.”

When it’s over Monday, only one club will be cherishing the outcome.

For the Heat, it’s a chance to move into the finals for the third straight year and keep hope alive of winning a second straight title. For the Pacers, it’s a chance to cap what would surely go into the books as one of the biggest upsets in NBA playoff history.
