I don't go to that board, because their hate-filled garbage makes it impossible to have a decent discussion. I've never seen anyone from here use that phrase, but if someone did, I'm sure it was in recognition that Marshall draws well in TV numbers across the country whenever it is lucky enough to be on ESPN. I'm not sure of this, but I think the GMAC bowl game vs. ECU is still in the top 5 watched college football games on ESPN2.
We know we don't have the name of an OSU, etc., but for a non-BCS school, I'd say Marshall is about as popular nation-wide as any other school in the same situation (i.e. Utah, BYU, Fresno, Memphis, etc.)
