What if, that is... Just a hypothetical thought.... People often pick on people that they actually like. People also pick on people more when they seem to be getting under their skin. Maybe Incognito likes Martin. Maybe Incognito is just one of those socially ******ed people who take it way too far, Martin took it very seriously and reached his breaking point. Maybe other players could see that he actually liked Martin, and just knew he was one of those guys who constantly has to outdo himself. Maybe they looked the other way because they thought Martin could see it as well, when in actuality it was burning him up at the deepest levels. It wouldn't make any of it okay, but it would explain how everything is going down a little bit better. If that were the case, communication would be the best thing for these two guys and the team.
When you mix a big-mouth, alpha-douche, A-hole like Incognito with a soft, over-sensitive patsy like Martin...this is what you get. Just a bad chemical reaction, take notes, move on...
