New England Patriots (white) & Philadelphia Eagles (green).
i haven't really been watching/listening all season other than hearing on the radio after or the next day if the Pats won or lost. you'll be hearing a lot about Tom Brady (quarterback) who recently had a hand injury-the one he throws with, & Rob Gronkowski (tight end) who got knocked around in the last game of the playoffs & ended up with a concussion but got the ok just in time to play.
i'm sure if you talk with some of the others before the game begins & just let them know you really don't understand much about the game they could fill you in. i just recommend not doing it during the game & mostly when there is a commercial or half time. best if you could get the rundown of terms before the game begins.
