Miami ? Only a year ago, everything in Dwyane Wade’s life was uncertain.

Former business partners had brought a combination of civil lawsuits, seeking somewhere around $100 million in what they said was the earnings potential of some failed deals. His yearslong divorce battle was still unsettled. Another courtroom fight was looming for custody of his two sons. And the free-agent period was fast-approaching.

“Very long year,” Wade said Saturday. “Very, very long year.”

Alas, it comes with a very, very sweet opportunity to close this chapter.

Wade is heading back to the NBA finals for the second time. When his Miami Heat open the series at home against the Dallas Mavericks — the franchise they beat in 2006 as well — on Tuesday night, it’ll be exactly 52 weeks after the four civil suits were settled in what was an overwhelming victory for his side.

With that, everything started falling into place.

Wade got his divorce. He stayed in Miami. He got LeBron James and Chris Bosh to join him. He got Udonis Haslem to stay with him. He got custody of his kids. The Heat won 58 games, endured some major bumps along the way, needed only 10 games to get past Chicago and Boston on the way to the Eastern Conference title, and now stand four wins from the ring.

“This would be the capper,” said Tragil Wade, the Heat star’s sister. “My mom has been saying this since his 29th birthday in January: ‘This will be the year and he will be rewarded. It’ll be in his favor. It will end in his favor.’ So even now, it’s all about belief. We’ve always had belief. When things are good, when things are bad, we always have to have belief.”

The first championship was great, sure.

After the last 12 months, for Wade, a second title would be monumentally more enjoyable.

“I know him better than anybody and I saw the toll that it kind of took on him,” Haslem said of the past year for one of his closest friends. “Through all that, he stayed professional. I think he’s used basketball as an outlet, as many of us do, and when it was all over and he was fortunate enough to get custody of his kids, I saw a light just shining around him.”

That light hasn’t always been there, of course. Wade’s story is well-known, starting with an incredibly rough upbringing in Chicago, leaning on his sister as the maternal influence for many years when his mother — Jolinda, now a minister who turned her own life around — wasn’t there for her children for an array of reasons.

Basketball was the escape, taking him away from the problems in Chicago to Marquette, then from Marquette to Miami. It has given him wealth and fame, and now — after a season unlike any other, where the Heat were as scrutinized as perhaps any team in NBA history — it has brought him to the cusp of a second championship.

“Basketball,” Heat coach Erik Spoelstra said, “has always been Dwyane’s sanctuary.”
