What happens if no offer is signed by a Restricted Free Agent by the deadline?

When a Restricted Free Agent (RFA) does not sign an offer sheet by the designated deadline, their rights revert back to their original team. This means that the team retains exclusive negotiating rights for the player, and they can offer the player a contract at their own terms. This process allows the team some control over the player's future and is particularly advantageous for the team if they wish to keep the player without other teams being able to sign them away.

The other options do not accurately describe the situation regarding Restricted Free Agents. For instance, if the player were to become a free agent or must enter the draft, it would not align with the rules governing RFAs. Thus, the reversion of rights reflects the intended balance between player mobility and team control in the context of the salary cap and free agency negotiations.
