What Incognito said to Martin in texts pales in comparison to what people say to you during a real game, and it is done to get you off your game. When a single play could be the difference in getting a million dollar contract or not getting signed at all, things WILL be said.
I personally think Martin's real problem is the game itself, and his inability to deal with that aspect. If I am right, it isn't Incognito, it isn't Miami... it is every Sunday, and we will never seem Martin in uniform again.
But I could be wrong... my wife says I am all the time. Time will tell.
