by no means I am an expert on the NFL suspension policy (I don’t think anyone is). However if I go by the letter of their policy they can’t suspend him for DWI. It is probably that Commissioners Protect the Shield stuff that got overhauled by the new CBA. So to say what the Commish will try in line with the new CBA I don’t know. But by the DWI Policy they have he can’t get suspended off that.
2.2 Violations of Law Involving Alcohol
The Commissioner will review and may impose a fine, suspension, or other appropriate discipline if a Player is convicted of or admits to a violation of the law (including within the context of a diversionary program, deferred adjudication, disposition of supervision, or similar arrangement including but not limited to nolo contendere) relating to the use of alcohol. Absent aggravating circumstances, discipline for a first offense will be a suspension without pay for two (2) regular or postseason games. If the Commissioner finds that there were aggravating circumstances, including but not limited to felonious conduct, extreme intoxication (BAC of .15% or more), property damage or serious injury or death to the Player or a third party, and/or if the Player has had prior drug or alcohol- related misconduct, increased discipline may be imposed. Discipline for a second or subsequent offense, absent aggravating circumstances, will be a suspension without pay for eight (8) regular and/or postseason games as determined by the Commissioner.
