A tidbit from the News Journal (DE paper)... This will only be the second time the I-AA Champion has defeated a I-A in the same season since 1998.

1999 Georgia Southern Oregon State L, 48-41
2000 Georgia Southern Georgia L, 29-7
2001 Montana Hawaii L, 30-12
2002 Western Kentucky Kansas State L, 48-3
2003 Delaware Navy W, 21-17
2004 James Madison West Virginia L, 45-10
2005 Appalachian State Kansas L, 36-8
2006 Appalachian State North Carolina St. L, 23-10
2007 Delaware Navy W, 59-52
2007 Appalachian State Michigan W, 34-32

(YSU won the title and beat Kent State in 1997 and UMass didn't play a I-A in 1998)

So this begs the question... is it worth it to play a I-A from a NC perspective?
