I agree that there are issues with the leadership within the Dolphins organization, but I can't believe you're willing to just handwave such a simplistic position on it.
Based on everything that's come out about the relationship between these two men, do you really think it is that simple? One day Incognito sends him that voicemail, and a few days later they are out go-karting together and laughign and having a good time, having their picture taken together and acting like everything's cool?
If anything is going to be learned from all of this, I think it's that Richie Incognito and Jon Martin are HUMAN BEINGS and that this situation is not as simple as one guy was mercilessly harassing another guy. Their relationship was obviously more complex than that and I think what we're seeing here is one of the many workplace meltdowns that happen all over America every day -- and the subsequent attempts to keep pay and benefits.
And yes, this stuff can happen even under good management. I don't know if Joe Philbin is a good leader or a bad one (I'm leaning toward bad), but it's just strange to me that you would so adamantly simplify the entire situation down to "Joe Philbin didn't know EVERYTHING that was happening? Terrible leader!" Because that's crap. It really is.
I know you've mentioned leadership in the marines, and all I can say is, that's got to be a little different. Not having been an officer in the Marine Corps, but having worked as a teacher when I was younger, and having served in a management position over adults as well, I can tell you that respecting privacy and boundaries can also be key elements of leadership and management. If Martin isn't going to open up and tell him these things, what is he supposed to do? Spy on their phone records?
And I can accept the argument that Martin didn't feel comfortable going to Joe, and that that's a strike on leadership. I'll buy that. But Martin apparently didn't feel comfortable going to ANYONE, including the union, and that to me indicates that maybe Martin is one of those guys who internalizes everything and can't go to anyone else for help. Those people are out there, and they are more common than you think. For a very long time, I was one of them.
