Did you read the texts back and forth? Incognito wasnt bullying him at all! He used coarse language, but he was trying to help him out and make him feel like one of the boys. Guys, and especially athletes "ball bust" all the time... if youre in a lockerroom and nobody is busting your balls... then nobody probably likes you, or considers you close enough of a friend to say outlandish s**t too.
If i met a dude for the first time today i wouldn't call him names and joke about his sister. If you heard me talk to my hest friend from 3rd grade, youd think we hate eachother!!! But were able to say that crap because we are friends. Incognito was trying to make him feel like one of the boys and boost his confidence. Anyone who read the back and forth texts would see it!
