According to McDermott, he had that conversation with Cole already. It hasn't stopped Cole.
I'm likely one of Cole's harshest critics on how he handles himself off the field, but I don't think he's at a cut level unless this is causing a problem within the locker room (or starting rumblings). I do think they need to have another sit down with him and explain they support him expressing himself, but that it does cause a distraction for the team and just how much this means to him compared to what they're trying to accomplish as a football team.
