The league's free agent signing day arrived Thursday, though the biggest free agents didn't rush to grab their pens.
Carmelo Anthony, Dwyane Wade and Chris Bosh might have been waiting on LeBron James before making their decisions.
There was no indication on when James planned to choose a team, so the Heat and Cavaliers waited, as did fans lining up outside James' Akron, Ohio, home, even while he was in Las Vegas at his basketball camp.
James was joined in Las Vegas by Heat teammate Dwyane Wade, espn.com reported. The two were spotted chatting and watching a pickup game together.
There was no timetable for James' decision, but with reports saying he would attend the World Cup final Sunday in Brazil, a decision before then seemed likely.
James and his agent, Rich Paul, met with Heat officials for more than an hour Wednesday in Las Vegas, espn.com reported. James and Paul were done meeting with teams, reports said.
Knicks president Phil Jackson had hoped the first signing day would finally bring a decision from Anthony. Jackson said he hadn't heard from Anthony since meeting with him a week earlier and Anthony had not responded to Jackson's text messages.
The Knicks offered Anthony a maximum-level contract, worth nearly $130 million over five years, at their meeting. Jackson said he had made perhaps five contract proposals to Anthony.
If James does leave the Heat, Bosh will sign with the Rockets, espn.com reported. Bosh has secured an offer for four years and $88 million from Houston.
Complicating the Bosh offer is restricted free agent forward Chandler Parsons signing a three-year offer from the Mavericks for more than $45 million, a deal Houston has until 11:59 p.m. Sunday to match. If the Rockets match, they lose the salary cap space for Bosh. They can keep Parsons, a former Gator, and still afford Bosh only if they sign Bosh first.
Kyrie Irving signed a five-year, $90 million extension with the Cavs after agreeing to terms last week, and the All-Star guard is under contract with Cleveland through 2019-20. The Cavs hoped securing Irving would make them more appealing to James.
