As the NFL contemplates the question of whether and to what extent the players deemed to have harassed Dolphins tackle Jonathan Martin should be punished, the league has a potentially major problem when it comes to Dolphins guard Richie Incognito.
The Collective Bargaining Agreement states that only one penalty may be imposed on a player.
Article 46, Section 4 — titled “One Penalty” — says that there shall be only (duh) one penalty: “The Commissioner and a Club will not both discipline a player for the same act or conduct. The Commissioner’s disciplinary action will preclude or supersede disciplinary action by any Club for the same act or conduct.”
That doesn’t make it right, or fair. Incognito could have created a potential mess for the Dolphins and the NFL by declining to convert his maximum unpaid suspension of four games to two games without pay and six paid games, which would have forced the Dolphins to bring him back or cut him late in the 2013 season. He allowed the team and the league to avoid that specific complication; even if he’s subject to further discipline for conduct unrelated to the harassment of Martin, Incognito deserves some consideration for not trying to force his way back to the field last season.
