Why? Tulane and Marshall are too much alike.
1. They both have green and white as their colors. The First Family dons their best green and white school clothes and we blend in. We do not stick out or even seem out of place.
2. The cheers are too similar. Whereas Marshall cheers: Green (one side of the stadium) matched by White (from the other side), Tulane cheers: Green matched by Wave. Even if there was a shout/cheer off between the two schools they would blend perfectly; it would sound like a Gather family reunion special rather than a Henry Rollins song.
I think those two reasons should compel the Athletic Director and the powers that be at Marshall to explore a different conference to call home.
