I've never had any issues with the Chiefs. I've actually tended to root for them over the years as they normally play the Chargers, Raiders and Broncos, all of which have been threats to the Pats for a long time. I really like the matchup in this year's SB too. I'm not rooting for or against anyone in particular and want to see a good game that comes down to the last play. All "feel good" stories for whoever wins as well.
