There are differences in those match-ups that you note. Rice and Houston were C-USA teams when we were trying to get into the league. Navy is a nationally know team so playing them was good PR even though we didn't win. UCA, Nichols and Grambling are FCS schools and those were 1 and done. In the case of ULM, they would want at least a 1 and 1. Now the home part would be equivalent to a Nichols but the away part would take the place of a Kansas or NC State. Whatever we might make on the additional, if any, ticket sales for the home game would be more than offset by the loss of payoff for an Illinois or Virginia. To put it simply, it ain't worth it.
