I work with a guy that formerly worked at UA. He's come in contact with the football players many times. He said that DJ is just a big ole teddy bear. As the previous poster said, very congenial, easy to talk to etc.
On another note, a story from the same guy...said that when Jesse came for a visit he wanted to know why we had so many rats running around campus, he'd never seen so many or the size of em. He was talking about the squirrels!
