My jaded prediction:
If KC wins, Detroit can only beat SF by being ahead of SF by two scores at the start of the 4th quarter and they'll be playing SF + the refs because the NFL doesn't want 2 teams from the midwest playing in a SB. So, I'm rooting for the Ravens even though I don't like the Ravens or Baltimore.... at all....not even a little bit, haha
Detroit has some key injuries, but I believe that the Lions believe in their season long, "Next Man Up" that it could be a good game and I hope it is.
Go Goff and Go Lions!
