People complain about the desk chairs all the time, but when a football player says it, it's a story? How was that even worth your girlfriend's friend passing it on to anyone? It says nothing whatsoever about his character.
I was in a class with Will Compton last spring, and one time he said his arm itched. He'll complain about anything and clearly doesn't deserve to be on scholarship.
It was a trivial and minor example. The point I was trying to make is that Nebraska players are treated like Gods, which everybody knows, and some of them are just downright terrible people with horrible personalities (not saying this is Aaron Green). It's not entirely their fault - it's part of the culture surrounding college football. All this had to do with anything is it makes sense to me when players get here and end up leaving - they're built up and put on pedestals, some of their attitudes reflect it at times, and when things don't go the way they expect they bail out.
But, if you'd rather be asinine, power to you.
