“Players can receive either the league-wide maximum [which for them would be approximately 35 percent of the cap] or their personal maximum [105 percent of their previous salary], which is greater. We won’t know the league-wide maximum for 2014-15 until July 2014, but right now, it’s $19,136,250.”

But that figure is expected to grow — and potentially surpass their “personal maximums” — because league revenues are projected to grow.

The Big 3 all sacrificed some salary in 2010 to leave the Heat with enough money to re-sign Udonis Haslem and add Miller. Whether they would be willing to do that again eventually is conjecture.

If all three opt out in two years, they would be eligible to sign five-year deals with 7.5 percent annual raises from the Heat, compared with four years and 4.5 percent pay hikes if they change teams.

Miller ($6.6 million), Haslem ($4.6 million) and Joel Anthony ($3.8 million) also have opt-out clauses in the summer of 2014 but seem unlikely to use them, and there’s a good chance Miller will have been amnestied by then anyway.

The Heat’s other challenge is the strong likelihood that regardless of whether it amnesties Miller, Miami will have only the $3 million taxpayer’s exception — not the $5 million exception — next summer and likely beyond in the Big 3 era, unless it dumps at least one player from among Haslem, Anthony and Chalmers.

That’s because non-taxpaying teams that use the $5 million exception have a hard cap that’s $4 million above the tax threshold ($74.3 million this season, likely in the $77 million range for 2013-14).

Arison has said he does not believe the Heat will end up making money for this past season despite winning a championship.

“Every year in [AmericanAirlines Arena] we’ve lost money aside from last year under the old collective bargaining agreement, because of LeBron,” Arison told CNBC. “This is a hobby and passion — it’s not a business.”

• Rookie second-round pick Justin Hamilton, who missed Miami’s first two Las Vegas Summer League games because of a hamstring injury, had four points, one rebound and five fouls in 14 minutes in Wednesday’s late-night 65-62 loss to Golden State. Terrel Harris shot 2 for 11 and is now 12 for 34 in three games. The Heat plays its fourth of five summer league games against San Antonio at 8 p.m. Friday.
