At this point, it is about longevity, nothing more.

Tuesday, the Miami Heat will play their 104th game since the 2012-13 season started. The only concern now is living to 105.

That was the sole theme as the Heat took flight deep into the night Sunday after an uneven week deep in the heart of Texas. Down 3-2 to the San Antonio Spurs in these best-of-seven NBA Finals, the Heat touched down in South Florida early Monday morning amid the comforting reassurance of the final two games of their season scheduled at AmericanAirlines Arena, as part of the 2-3-2 scheduling unique to the NBA Finals.

But the recurring theme before they took flight, before given Monday off by coach Erik Spoelstra, was that in order to get to Thursday's Game 7, they first must accomplish in Tuesday's 9 p.m. Game 6 what they couldn't in Sunday's 114-104 loss at the AT&T Center that put them in this 3-2 hole in the first place.

"Can we put together our best game on both sides of the floor in Game 6?" Spoelstra said. "We do feel good that we're going home for that game. But we've got to earn back that home court. And so our focus is only on the next game."

One on hand, only three teams down 3-2 in the 2-3-2 format adopted in 1985 have come back to win the final two games of the NBA Finals at home. On the other, of the 17 Game 7s in the NBA Finals, the home team has won 14.

In a Finals full of moments both of dominance and dreadfulness, with each team producing a pair of blowout victories, comes one final twist: While the Spurs are now up in the series, the Heat have been posted as the favorite to win Game 6 and certainly would be the same for Game 7 should they get there.

Yes, it has been that type of two-week rollercoaster, one replete with lineup changes on both sides, the Heat possibly next to shuffle the deck amid what has turned into a failed bid with Mike Miller as a starter.

The focus now is singular, a focus the Heat have not required since Game 7 of the Eastern Conference finals against the Indiana Pacers.
