Favorite MLB/NFL teams?

I live in KS and have always liked chiefs and royals forever just not as much as other teams. I even liked the Broncos and Reds at one point (brainwashed by a friend). I now like the Yankees, Cowboys, Knicks, Chiefs, and Royals. I'd like the Chiefs and Royals to be my #1 teams but I still like NY and Dallas and I don't wanna be a "bandwagon" fan. Any ideas on what to do???
