Unofficially, the Hawks have tendered a qualifying offer to the following players:
This makes them restricted free agents and will carry a cap number until they are signed and gives the team the right of first refusal.
This means that Othello Hunter and Thomas Gardner have not received those offers and will now be unrestricted free agents, free to run, and run, and run to the team of their choice---with no way for the Hawks to stop them.
The Hawks will, in both cases, have the ability to initiate a sign and trade---which means the Hawks will also hold a cap number on these players until they are signed. If the team wants to free themselves of that cap number, they must renounce the rights to those players and the Bird rights that go with them.
This is also the case with their current unrestricted free agents (Zaza Pachulia, Mike Bibby, and Ronald "Flip" Murray).
We will update when we go final on the list and we thank @atlanta_hawks for the update!
