Chris Bosh, LeBron James (Robert Mayer, USATODAY Sports)

Recent momentum has made it appear ever-likely that LeBron James and Chris Bosh will spurn the Miami Heat in free agency for the Cleveland Cavaliers and Houston Rockets, respectively. Pat Riley, though, doesn’t seem worried – he’s confident the Big Three he assembled four years ago will ultimately return to South Beach.

Jeff Zilgitt and Sam Amick of USA TODAY report that the Heat’s Godfather is undeterred by the interest James and Bosh have in other destinations and remains confident they’ll re-sign with Miami.

This much is clear: Riley is confident James, Chris Bosh and Dwyane Wade will return, according to people who have had phone conversations with Riley in the last week. The people spoke to USA TODAY Sports under the condition of anonymity because of the sensitive nature of the conversations.

Speculation that James will sign with the Cavaliers has ramped-up in the past 48 hours due to a combination of legitimately sourced intel and typical internet frenzy. Bosh, meanwhile, is said to be considering a maximum contract offer from the Rockets after it was previously reported that he’d prefer such a deal to staying with the Heat for a sizable pay-cut.

But Riley’s supposed confidence isn’t the only recent noise suggesting both players are more likely to re-up with Miami than the surface indicates. LeBron will meet with Riley and Heat representatives in Las Vegas as soon as today, and Bosh still wants to play with James for the Heat.

And though Miami’s agreements with Josh McRoberts and Danny Granger yesterday aren’t the huge free agency splashes for which it was hoping, both are ideal fits for the Heat from on-court and financial perspectives. And McRoberts not only accepted his new deal with a belief LeBron will be his teammate, but James was aware Riley and company were pursuing him, too.

Of course, this is all conjecture until James or Bosh agrees with the Heat or another team. Their insistence – along with Wade’s – to be paid at market value or close to it while remaining in Miami has limited the flexibility Riley needs to add the caliber of players they supposedly want. McRoberts and Granger are nice complementary pieces, but hardly Luol Deng or Pau Gasol, let alone Carmelo Anthony.
