Ray Allen will give the Celtics "every chance of re-signing him," but he has been in contact with this summer's top-tier free agents.

Allen's conversations with Boston have been "productive and cordial," a source told Ken Berger of CBS Sports.

Like other free agents, Allen doesn't think he'll be able to get a complete picture of his value until guys like LeBron James, Dwyane Wade and Chris Bosh reach agreements.
