He's been vocal about not liking the way he's being used on the field, nebraska's playcalling, and his dad is extremely vocal and critical of nebraska. He also deleted a lot of tweets right before he announced he was leaving.
When Robinson quit he had a lengthy statement on twitter about how he was "the face of the program" but the way nebraska was using him didn't fit the way he wanted NFL scouts to see him play. Then he deleted that one and posted a new one basically thanking the program. So not only is he a selfish cuntwaffle, he's a spineless selfish cuntwaffle who can't own up to the words he speaks.
Not a team player at all, only concerned about himself, and his family is a shit show too. Typical nebraska recruit.
There is zero, and I mean Z E R O chance KF or Brian would even give the kid directions through Iowa as he leaves nebraska, let alone entertain the idea of him putting on an Iowa uniform.
