Minnesota will never win the SB. It's the FF Cafe Gods way of payback for the endless homerism demonstrated by what appears to be an over-whelming Viking fan base. Please understand that I am only joking and acually admire your undaunted enthusiasm. As a Detroiter I tend to be very cynical and sarcastic when it comes to the outlook for my teams.
The Lions actually have the better chance. If Joey Harrington, Charles Rogers, Az Hakim play like they're expected and they find a running game, and if Jauron works wonder with a soft D, the Lions should contend in 3-5 years. The Vikes D is too soft and Culpepper/Moss tandem will start slowing down before they get it turned around, barring any Tice magic. (which I think he used all of to keep his job). The Pack doesn't have the consistency at QB. Favre, unlike most cheese products, will not get sharper with age.
DaBears are...well, DaBears. Dumb upper management will keep them down. Any other questions about the future of the NFC North?
I think, therefore I am. I think fantasy, therefore I am unreal?
