ECU will probably always be an outsider, but once they do that pressbox project and make several substantial additions to their "Vanier" their stadium will be pretty legit, it's already not bad now except for that pressbox. If they have a good to decent team they'll put 45,000 plus in their for most games, which isn't bad considering their only T-Shirt fans are in their immediate geographic area.
Their likely scenario once conference realignment shakes out is a 'best of the rest' conference with Memphis, CFU, La. Tech, So. Miss, Tulsa, SMU, Houston, Temple, I could also see some MAC schools in there as well.
