It is important to let this play out.
Things to note:
The owners are not subject to the CBA which this falls under.
The gambler is not subject to the Personal Conduct Policy which this falls under.
The PED user is not subject to the Personal Conduct Policy which this falls under.
The ball deflator is not subject to the Person Conduct Policy which this falls under.
All those comparisons are not applicable in this instance.
However, all of those comparisons are applicable in the court of public opinion.
The MOST notable legitimate comparisons are Big Ben (1 accusation - 6 games) and Zeke Elliot (1 accusation - 6 games)
Sue Robinson's quote "Egregious misconduct"
I think this will be upped by 2-6 games and he will be fined and he will be required to attend counseling (which he should do regardless).
The NFL won't want to look weak, but will not want this drawn out all season again. So they won't go for the full season, but they will increase it. But not by so much as to draw appeals from the NFLPA.
8-12 games.
IMHO
