This is nothing new. We've see plenty of examples where people (not just athletes) have been punished by their employer for actions against their published code of conduct, from suspensions through dismissals. Without laws being broken."Should he own or possess a firearm, Morant also has a duty under the same provision to provide the Grizzlies proof that he has the proper license and registration."
Kind of hard to show "proper license and registration" when Colorado requires neither (it's an open carry state), nor does Tennessee when he lives.
Be interesting to see what happens when the union challenges the suspension as no laws were broken and he wasn't on team business at the time. Saying he was on a road trip is really stretching the rule.
As for a road trip not qualifying as team business, I'd say it definitely does as far as the CBA language is concerned: “whenever a player is traveling on any NBA-related business.....".
Since it apparently means that much to him maybe he should limit his social media posts waving his gun around to the offseason.
