This picture means absolutely nothing in the grand scheme of things. However, two points.
1) I have read on message boards that Scott and Bo do not get along so no way in hell would Bo ever hire Scott or Scott would never work for Bo. Kind of flies in the face of that at least a little.
2) Biggest question about this, who originally tweeted the picture? If it was simply a fan that saw them and wanted a picture of three major people associated with Husker football....then it means nothing other than a cool picture for him/her.
Now, if it were tweeted out by one of these three....why? Was it to sort of poke a finger at the people who believe #1? That's what it would seem to me. Not much more than that at this time.
