We should also do the opposite of this as well. Your favorite team that's not your primary rooting interest.
Least - Miami - no idea why.. have also just disliked the Hurricanes and their teams.. even since the 90's
Favorite not primary - Wisconsin - loved their style of ball for a long time. Always focused on winning the game in the trenches. Always felt like a great midwest football program that was just country strong in the trenches, always had a beast at running back and defensively was just "tough." Maybe not top end talent, but good enough talent mixed with toughness that was good to watch..
