A restricted free agent is any veteran player with three accrued seasons, but with less than four, at the conclusion of the player's expiring contract. Players are free to negotiate and sign an offer sheet with a new team, subject to the right of first refusal from the original team, who may make a qualifying offer on or before the first date of the restricted free agent signing period, which is at any point before the start of the 2014 league year (4 p.m. ET on March 11).

Other teams may sign that player to an offer sheet and the original team has seven days to match and if they don't, they may receive compensation based on the tender applied to that player. If no team signs the player to an offer sheet, then that player signs his tender and receives the compensation listed below for the 2014 season.

The four offers teams can tender restricted free agents are, per Article 9, second 2 of the Collective Bargaining Agreement:

Right of First Refusal Only. One-year Player Contract with Paragraph 5 salary of at least $1.323 million. No compensation is applied to the original team if another team signs this player to an offer sheet. This is usually applied with players that entered the NFL as an undrafted free agent; Right of First Refusal and Draft Selection at Player’s Original Draft Round: One-year Player Contract with a Paragraph 5 Salary of at least $1.431 million for right of first refusal and original draft round compensation. If the restricted free agent entered the league in the sixth round of the NFL draft, the original team receives a six in the next NFL draft from the new team. Right of First Refusal, One Second Round Draft Selection: One-year Player Contract with a Paragraph 5 Salary of at least $2.187 million for right of first refusal and second draft round compensation. No matter how the restricted free agent entered the NFL, the original team receives a second-round pick from the new team if said new team signs the player to an offer sheet that the original team isn't willing to match. Right of First Refusal, One First Round Draft Selection: One-year Player Contract with a Paragraph 5 Salary of at least $3.113 million for right of first refusal and first draft round compensation. No matter how the restricted free agent entered the NFL, the original team receives a first-round pick from the new team if said new team signs the player to an offer sheet that the original team isn't willing to match.

A quick note that the restricted free agent could receive 110 percent of his 2013 salary if the compensation is higher than the predefined compensation numbers. More about Restricted Free Agents (really boring stuff), via the CBA.

Section 3. Offer Sheet and Right of First Refusal Procedures:

(a) Offer Sheets. When a Restricted Free Agent receives an offer to sign a Player Contract from any Club (the "New Club") other than the Prior Club, which offer the player desires to accept, he shall give to the Prior Club a completed certificate substantially in the form of Appendix B, attached hereto (the "Offer Sheet"), signed by the Restricted Free Agent and the New Club, which shall contain the "Principal Terms" (as defined below) of the New Club’s offer. The New Club and the player must specifically identify in the Offer Sheet those provisions they believe are Principal Terms. The Prior Club, within five days from the date it receives the Offer Sheet, may exercise or not exercise its Right of First Refusal, which shall have the legal consequences set forth below.

(b) First Refusal Exercise Notice. If the Prior Club gives the Restricted Free Agent a "First Refusal Exercise Notice" substantially in the form of Appendix C, attached hereto, within five days from the date the Prior Club receives an Offer Sheet, but not later than one day before the Draft (unless the parties agree otherwise), such Restricted Free Agent and the Prior Club shall be deemed to have entered into a binding agreement, which they shall promptly formalize in a Player Contract, containing (i) all the Principal Terms (subject to Subsection (e) below); (ii) those terms of the NFL Player Contract not modified by the Principal Terms; and (iii) such additional terms, not less favorable to the player than those contained in the Offer Sheet as may be agreed upon between the Restricted Free Agent and the Prior Club.

(c) No First Refusal Exercise Notice. If the Prior Club does not give the Restricted Free Agent the First Refusal Exercise Notice within the applicable period, the player and the New Club shall be deemed to have entered into a binding agreement, which they shall promptly formalize in a Player Contract, containing (i) all the Principal Terms; (ii) those terms of the NFL Player Contract not modified by the Principal Terms; and (iii) such additional terms, not less favorable to the Restricted Free Agent than those contained in the Offer Sheet, as may be agreed upon between the Restricted Free Agent and the New Club (subject to Section 5 below), and the Restricted Free Agent’s Prior Club shall receive from the New Club the Draft Choice Compensation, if any, specified in Section 2 above of this Article. Any Club that does not have available, in the upcoming Draft, the selection choice or choices (its own or better choices in the applicable rounds) needed to provide Draft Choice Compensation in the event of a timely First Refusal Exercise Notice may not sign an Offer Sheet in such circumstances. The player and the New Club may not renegotiate such Player Contract to reduce the Salary in such contract until after the end of the first regular season covered by the Contract. Neither the player nor the New Club may exercise an option in such Player Contract that reduces Salary in the first League Year of such contract until after the end of the first regular season covered by the Contract.

(d) One Offer Sheet. There may be only one Offer Sheet signed by a Restricted Free Agent outstanding at any one time, provided that the Offer Sheet has also been signed by a Club. An Offer Sheet, before or after it is given to the Prior Club, may 40 be revoked or withdrawn only by the Clubs upon the written consent of the Restricted Free Agent. In either of such events, the Restricted Free Agent shall again be free to negotiate and sign a Player Contract with any Club, and any Club shall again be free to negotiate and sign a Player Contract with such Restricted Free Agent, subject to the Prior Club’s continued Right of First Refusal and/or Draft Choice Compensation as described in this section.

(e) Principal Terms. For the purposes of this Article (and Article 10), the Principal Terms of an Offer Sheet shall include only:

(i) Salary, which shall consist only of (a) the fixed and specified dollar amounts the New Club will pay, guarantee or lend to the Restricted Free Agent and/or his designees (currently and/or as deferred compensation in specified installments on specified dates) in consideration for his services as a football player under the Player Contract (i.e., signing bonus, Paragraph 5 Salary, and reporting and roster bonuses); and (b) Salary that is variable and/or is subject to calculation only upon the following bases: (1) based upon the performance of the Club extending the Offer Sheet (only those incentives which are "likely to be earned" by the player if he enters into a Player Contract with the New Club, pursuant to Subsection (c) above, must be matched by the Prior Club for the purpose of exercising a Right of First Refusal, and such incentives may not exceed 15% of the Salary in the Offer Sheet); and (2) League honors listed in Exhibit C to Article 13; and

(ii) Any modifications of and additions to the terms contained in the NFL Player Contract requested by the Restricted Free Agent and acceptable to the New Club, that relate to non-compensation terms (including guarantees, no-cut, and no-trade provisions) of the Restricted Free Agent’s employment as a football player (which shall be evidenced either by a copy of the NFL Player Contract, marked to show changes, or by a written brief summary contained in or attached to the Offer Sheet).

(iii) Notwithstanding Subsections (i) and (ii) above, no Offer Sheet may contain a Principal Term that would create rights or obligations for the Old Club that differ in any way (including but not limited to the amount of compensation that would be paid, the circumstances in which compensation would be guaranteed, or the circumstances in which other contractual rights would or would not vest) from the rights or obligations that such Principal Term would create for the Club extending the Offer Sheet (i.e., no "poison pills").

(f) No Property or Investments. A Club may not offer any item of property or investments other than Salary as part of the Principal Terms contained in an Offer Sheet.

(g) Incentives. For those incentives which are based on Club performance, only those incentives which are "likely to be earned" by the player if he enters into a Player Contract with the New Club, pursuant to Subsection (c) above, must be matched by the Old Club for the purpose of exercising a Right of First Refusal.

(h) No Consideration Between Clubs. There may be no consideration of any kind given by one Club to another Club in exchange for a Club’s decision to exercise or not to exercise its Right of First Refusal, or in exchange for a Club’s decision to submit or not to submit an Offer Sheet to a Restricted Free Agent or to make or not to make an offer to enter into a Player Contract with a Restricted Free Agent. Nothing in 41 this Subsection shall preclude a Prior Club from entering into a Player Contract with a player subject to a Tender, and subsequently trading that player under that Player Contract to another Club, provided that the player and the NFLPA must approve in advance any such trade that takes place during the Signing Period. If a Club exercises its Right of First Refusal and matches an Offer Sheet, that Club may not trade that player to the Club that submitted the Offer Sheet for at least one calendar year, unless the player consents to such trade.

(i) NFL Only. No Right of First Refusal rule, practice, policy, regulation, or agreement, including any Right of First Refusal applicable to any Restricted Free Agent or Transition Player pursuant to Article 10 below, may apply to the signing of a Player Contract with, or the playing with, any club in any professional football league other than the NFL by any Restricted Free Agent (except as agreed by the player in the circumstances set forth in Section 5 below). This prohibition applies to any Right of First Refusal described in this Agreement (except as described in Section 5 below).

(j) No Assignment. No Right of First Refusal may be assigned to any other Club (except as provided in Article 6, Section 7 or as agreed by the player in the circumstances set forth in Section 5 below). This prohibition applies to any Right of First Refusal described in this Agreement (except as described in Section 5 below), including any Right of First Refusal with respect to Restricted Free Agents, Transition Players, or Drafted Rookies described in Article 6, Section 5.

(k) Copies. Promptly upon but no later than two business days after the giving of an Offer Sheet to the Prior Club, the Restricted Free Agent shall cause a copy thereof to be given to the NFL, which shall notify the NFLPA. Promptly upon but no later than two business days after the giving of a First Refusal Exercise Notice to the Restricted Free Agent, the Prior Club shall cause a copy thereof to be given to the NFL, which shall notify the NFLPA. At any time after the giving of an Offer Sheet to a Prior Club, the NFL may require the New Club to cause a copy thereof to be given to the NFL and the NFLPA.

(l) Disputed Offer Sheet. In the event of any dispute regarding whether a term in an Offer Sheet is or is not a Principal Term that must be matched, including any dispute regarding whether a term is an impermissible poison pill designed to discourage or prohibit the Prior Club from exercising a Right of First Refusal, the dispute shall be presented to the Impartial Arbitrator for expedited resolution under Section 4 below. The Impartial Arbitrator shall identify all of the terms that would have to be matched by the Prior Club, and the Prior Club shall have two days after such decision in which to exercise its Right of First Refusal.
