Signing day arrived Thursday in the NBA, though the biggest free agents didn’t rush to grab their pens.

Carmelo Anthony, Dwyane Wade and Chris Bosh might be waiting on LeBron James — isn’t everybody? — before making their decisions.

There’s been no indication when James plans to do so, so Miami and Cleveland waited anxiously — as did fans lining up outside James’ Akron, Ohio home, even while he was in Las Vegas.

Knicks President Phil Jackson was hoping Thursday would finally bring a decision from Anthony.

“But I expected one yesterday and the day before yesterday,” Jackson said at the Knicks’ summer league practice in Las Vegas. “But no, we’re waiting.”

In the meantime, Kyle Lowry and Marcin Gortat signed contracts to remain with their teams, while Chandler Parsons and Gordon Hayward inked offer sheets that could land them on new ones.

Teams and players could negotiate and agree to deals since July 1, but contracts couldn’t be signed or trades made until Thursday, after the moratorium period ended and next season’s salary cap was set.

The Rockets are one of the teams believed to be considering Chris Bosh if he does opt to leave Miami, which could affect how they deal with Parsons.

They also met with Anthony, whom New York wants to keep.
