Diamond has been Blue this whole time, he is just playing out his recruitment for the documentary crew that has been following him. If he would have ended his recruitment at the BBQ over the summer, that would have been a boring film. Instead, he has drawn it out until the last possible moment, keeping everyone guessing the entire way. Now that people assumed Michigan was going to be the pick on Friday, he has made it seem as though they have faded so people will be suprised when he does, in fact, go Blue. If the whole football thing doesn't work out for him, maybe his true calling is as a director.
"The University of Illinois is also in turmoil. The university sports an Interim Chancellor, an Interim Athletic Director, and an Interim Football Coach; the game will be played at Soldier Field, making this an Illini Interim Home Game."
