An exciting rivalry to see is the San Francisco 49ers and the Seattle Seahawks. More imporantly, I love to see quarterbacks Colin Kaepernick and Russell Wilson. They have some of the same qualities such as stong arms and quick feet but their styles are a little different.
Colin uses the pistol offense which is hard for a quarterback to defend whereas Russell uses a more traditional type of offense.
I have high expectations for both in the upcoming season and I believe they will create an even more enthralling experience.
