“Scott Frost is my boy,” Keyshawn Johnson said. “I don’t think people even understand — I played with Frosty. I know Frosty. We know each other. This is not — I didn’t know Bo Pelini. I had no relationship with Bo Pelini whatsoever, at all, period. But I know Scott Frost. I have a relationship with Scott Frost, OK? That’s what it is."
“My son is going back to Lincoln, Nebraska, as of now, in the month of January, and [will] be playing with the football team and all of his friends.”
