If I were Notre Dame, I'd be concerned that their network might be making other arrangements long term. Anybody remember how long the Notre Dame contract with NBC is? They might want to get into the Big Ten before they turn into the 21st century version of Fordham.
From Wikipedia:
In 1991, the initial contract was sold to NBC for $38 million for 5 years or $1.2 million a game. Notre Dame got half of the latter figure and its opponent got the other half. http://en.wikipedia.org/wiki/Notre_Dame_Football_on_NBC#cite_note-0 In June 2008, NBC signed a contract extension, which covered from 2011 to 2015.http://en.wikipedia.org/wiki/Notre_Dame_Football_on_NBC#cite_note-1
