I have no knowledge of football. Can somebody brief me on what I should know about the upcoming superbowl?

Spare me the whole “I’ll brief you: Colts are gonna WIN! WOOO!”

I want to know who the key players are on each team and why, any drama that may have happened during each teams season, key games, highlights…basically just some conversational topics so that I can look like I at least keep my finger on the pulse of the NFL – even if extremely lightly.

I’m hoping this question is not misinterpreted as “Who do you think is going to win the superbowl??”
