Of course there will be consulting going on, Spurrier is a great coach with a ton of knowledge, he and Shawn Eichorst are friends, and are attending a football game together. So yes, consulting will be talked about, they will talk football, it's what friends do at a football game. It can only help, so who cares.
This is a neat deal, a legendary coach getting his first visit to Lincoln to catch a game. My hunch is Spurrier will thoroughly enjoy it, and we may get some good kuddos quotes about the atmosphere on Monday.
Although, I like the move, I think its a good thing Eichorst did, in the grand scheme of things given the current state of everything, very odd timing. So of course there will be speculation.
