But for that to happen, they would have to be made aware of it!
It's entirely possible that this situation involves the one set of circumstances known to date in which: 1) someone like Martin was displeased, 2) he didn't make it known to his teammates, so there was no perception on their part that anything needed to be done, and 3) he didn't keep it to himself.
It's possible that in every other similar scenario in the history of the NFL, the displeased player: 1) made his state of mind known to some entity within the team, which then solved the issue, or 2) never made it known to anyone, ever.
What we could have here is a player who didn't make the issue known to anyone within the organization, and, instead of suppressing the issue within himself and just going with the flow, he left the team and went to the media.
The perception that other locker rooms could've prevented something like that I think is a serious overestimation of their abilities.
But again, the problem with these sentiments is that they start with the idea that people within the organization were aware of Martin's state of mind, when in reality we've heard no evidence of that to date.
These other players need to start instead with the question, "if I and my teammates were not aware that a player was feeling this way, could we have intervened in a way any better than the Dolphins did?"
But instead that question isn't asked. It's as if the team must have been aware Martin was distressed, which I think is an erroneous assumption, given the evidence to date.
