Just like Ricky Williams said, the right thing to do if the NFL becomes overwhelming is just leave and take a break. You don't have to demonize anyone to do it. Martin is the one firing a shot over the bow by throwing the team under the bus. You can see how angry the Dolphin players were by that. This goes beyond Incognito, the sportscasters keep saying that, and for Martin's attorney to get any traction with a lawsuit against the Dolphin organization, they'd have to prove they were aware of an issue and that Martin went to management to rectify the situation and that they failed to. I'm not so sure he can prove that.
It seemed like a clever move at first, to target one player (Incognito) as the primary evildoer, but sometimes you should be careful what you wish for. Once Incognito gets over being stunned by this, he's going to get revenge by digging up everything he can. While he seems like the type that has trouble locating clean underwear, much less voicemail recordings,...it's possible other people on the team, or other people he knows may have stuff and will happily turn it over to his camp. Martin is burning a lot of bridges with people and that may result in more resources for Incognito.
The drama, I'm afraid, will not end just yet.
