Well, given that I grew up occasionally visiting along the New Indianorleanapolis beltway, I have to say that I've been an undyingly loyal fan of the Colts and Saints ever since my lengthy weeklong stay in Baltimore, er, visit to Mardi Gras.
Yes, those perennial losers may be for real.
I'm still not a big fan of either but, right now, I'd say Bengals-Colts AFC, Saints-Vikes NFC.
