LeBron James, Chris Bosh and Dwyane Wade plan on offering Pat Riley a window to carry out his plan on upgrading their supporting cast, according to sources.

All three players have opted out of their deals to become free agents.

The Heat began their offseason moves by acquiring the draft rights to Shabazz Napier, who James is known to be extremely fond of as a player.

James is also expecting a max contract, while Bosh and Wade will likely sign for less. Wade is expected to take significantly less money.

"Everybody has their [contract] number and has left a little bit of room to let [Riley] maneuver," one source briefed on the contract discussions said.

As one general manager told Yahoo Sports, "Right now, it's clear they're buying time for Riley to go out and hit the market."

Rich Paul has avoided any communication with teams ahead of James' free agency in order to abide by NBA rules on holding talks before the official start period of 12:01 AM on Tuesday.
