Have you ever been in an empty, or even half-empty venue? Stadium, movie house, restaurant, factory, Amusement Park? The emptiness can't be hidden. They are depressing. They taint everything they come in contact with; people, programs, institutions.
That being said, if there is reasonable (there are never guarantees) data to suggest that we can fill 50-60K seats for ECU, Memphis, Tulane, etc. Then, go for it. I spent a good portion of my corporate life being chided about using shareholder money on seemingly risky ventures. Believe me, I was the aggressive one in the room; the one who induced the eye rolls. The problem I have is that our present situation makes bringing Michigan type games to the Rent more than problematic. I think the proper affiliation would allow us to, occasionally, fill 70K seats. I'm that optimistic. Moreover, I think that prospect can be sold. The problem I have is that an unfortunate, ill-timed expansion would have the effect of possibly killing more than UCONN FB. Even the most aggressive of us are taught to avoid the mistake from which there is no recovery.
Of course this is all moot. I'm one who believes that conference affiliation and stadium size have already been determined. Just awaiting an announcement.
