Incognito will be fine. I wouldn't even be totally surprised if he's playing for Miami next year. Incognito's favorability among players is much higher than Martin's. Not sure how coaches feel, but I have a hard time thinking that 32 NFL coaches would shut him out.
This whole thing continues to be misunderstood, but it began as a misunderstanding when everyone wanted to put 100% of the blame on one person instead of a locker room of guys that together put one of their own players in a corner.
Anyone that thinks bullying wasn't going on is incredibly naive. Even some of Incognito's biggest defenders know bullying was going on, because their defense of Incognito is that this type of hazing is commonplace in the NFL. As far as the back and forth texts: Put yourself in that situation from Martin's vantage point. How would you respond to such aggressive hazing and threats? Probably by firing back right?
I hope that both Martin and Incognito are on NFL rosters next year, and I hope more coaches start adopting the kind of environment Pete Carroll has which does not tolerate player abuse. I would like to think this whole episode provided ample motivation for coaches who want to avoid massive potential distractions, nevermind the fracturing in the locker room. No matter how you look at it, these kind of behaviors have no potential upside, it's just pure downside.
I do think Martin's use of texts without context is petty bullshit. It appears he was out for revenge. But having been through a similar experience, I kind of think Incognito got what he deserved (suspended for a few games, missed a few game checks, got put through the media-wringer) so it's hard to feel too bad for him. I think if James Carpenter had quit because Paul McQuistan and other lineman had acted this way, I don't think Pete would have taken that lightly and as such I think the consequences Incognito faced are fair. It's the other guys in that locker room who did wrong and got away scot-free who are the big winners in all this.
I also think that in Incognito's warped mind, he really thought that he truly was Martin's buddy, and that everything he said was in good fun. Having never been on the receiving end of that kind of severe, daily harassment he doesn't understand how devastating it can be, especially when it's a group effort. He thought they were having fun. He didn't know the hurt he was causing, the resentment he was building. If I were Incognito I'd just be thankful that Martin doesn't have the same interest in big guns as Aqib Talib or Aldon Smith. I interpreted Martin's decision to walk away as an admission that he was near the point of losing emotional control, and when people have nervous breakdowns it can get pretty scary depending on the person. Then Martin pulled some petty revenge bullshit and the dog was officially wagged.
