Alvin Kamara pleads no contest to lesser misdemeanor charge, jury trial is cancelled; civil suit also settled on confidential terms
I think that makes sense.
The policy says six games for violent conduct that results in felony charge(s). He was charged with felonies. But there's also a tradition of deferring to the result of the criminal case and not the charges. For example, a DUI charge that is later dismissed or reduced to something else doesn't get the 3-game suspension per the policy (which is also based on being "charged").
Kamara's felony charges go away so I think the league defers to that on the mandatory 6-game suspension. If the wasn't pretty clear video, I'd say he might even get 1 game, but I wouldn't be surprised if it's 3, which seems to sort of compromise at half. If Kamara agrees not to appeal, that might be way it goes down.
