Marshall discussed the issue with reporters Wednesday, explaining that players who show vulnerability open themselves up for issues in the locker room.
"(What's) going on in Miami goes on in every locker room," Marshall said. "But it's time for us to start talking. Maybe have some group sessions where guys sit down and maybe talk about what's going on off the field or what's going on in the building and not mask everything. Because the (longer) it goes untreated, the worse it gets."
"Obviously the situation that's going on is unfortunate, and anytime a guy gets pushed to that level of not wanting to play football then something has to be done," he said. "I think it's something that we can all learn from."
